** gw3 - I disagree with this. We should use the name that is used to describe the region in the paper, rather than making up our own names. I have had to go back and re-annotate regions after Xiaodong found problems with my stuff several months after I had originally done it and I really needed to be able to unambiguously identify which region the paper was talking about by using the Public_name field and matching this up to the name of the region in the paper. Users may well need to do this as well if they are reading the paper and looking at the Features marking up the regions.

* Gary and I are staying at the Ramada - 800 Morrissey Boulevard, Freeport St, Boston, MA 02122 US
 +
* We arrive in Boston on Saturday evening and fly home on Wednesday night.
 +
* What time shall we meet on Monday morning and where do we go?
 +
**I (Xiaodong) can pick up you guys at Harvard square T station (red-line, info center on the square) at say 9:30 am. We can walk to my office.
 +
* Can you confirm that we have office space with internet access? I will bring my Macbook. Hopefully I can tunnel into my Sanger working space.
 +
**Enough office space for sure. Internet access through Harvard guest. They won't allow you to access other ways.
 +
* Thanks Xiaodong, I'm bringing my chromebook - Gary

** The Features WBsf919641 and WBsf919607 are at the same position. Both are DAF-3 binding sites. WBsf919641 has Method "binding_site", WBsf919607 has Method "TF_binding_site" which I think is more correct as DAF-3 is a TF. WBsf919641 used the paper WBPaper00004526, WBsf919607 used the paper WBPaper00003384. WBsf919641 is associated with WBGene00202278, WBsf919607 is associated with WBGene00003514 (myo-2). The paper WBPaper00004526 appears to about a PEB-1 binding site, not a DAF-3 site. I made the Feature WBsf919609 for the PEB-1 site based on WBPaper00004526 in the last round of curation. Something not right here???
 +
*** Follow-up from Mary Ann. I agree Method for WBsf919641 should be TF_binding_site. Associated_with_gene should be updated myo-2 (this is an error). So term is not right either. These then become duplicate entries.
 +
*** Resolved: WBsf919641 merged into WBsf919607 - GW
 +
** The Features WBsf019227 and WBsf038813 and in the same position, but opposite strands. They both are for a LAG-1 binding site associated with gene lin-11. One from paper: WBPaper00005357, other from WBPaper00032298. WBsf019227 needs to be retired and merged into WBsf038813.
 +
*** Follow-up from Mary Ann. We have no merged_into tag structure in Feature. We have History tag and could add a Comment there.
 +
**** We have a merged_into tag structure in Feature. - GW
 +
*** Resolved: WBsf019227 merged into WBsf038813 - GW
 +
** WBsf038819 has a Method of 'regulatory_region', but the Public_name and Description describes it as an Enhancer. Which is it?
 +
*** Fixed by Mary Ann. Changed Method to enhancer.
 +
** WBsf919669 is an Enhancer, but it has a tag for a Transcription_factor WBTranscriptionFactor000101. It is far too large to be a binding site for a transcription fact. I think this tag should be removed.
 +
*** Follow-up from Mary Ann. lag-1 does bind somewhere in this region, but the paper does not allow me to specify exactly where. Q. Should we curate these then? I think we should, but should maybe add suitable Remarks.
 +
** 393 out of the 500 TF_binding_site Features have an incorrect SO_term tag. It should be set to: SO:0000235
 +
*** Follow-up by Mary Ann. This seems really high. I wonder whether TF_binding_site was not a recognised SO term when some of these were curated, especially the older ones. This (and other consistency checks) should be added to a script we can run.
 +
*** Resolved: all TF_binding_sites with SO_term SO:0000409 changed to SO:0000235 - GW
 +
** 10 Features with Method = "TF_binding_site" are lacking a Transcription_factor tag.
 +
*** Follow-up by Mary Ann. Maybe it's not clear in the paper what the TF is? Something to add to consistency check.
 +
*** Resolved: the  MEC-3/UNC-86 heterodimer has been added - GW
 +
* how many 'Method's for feature? enhancer, regulatory_region, TF_biding_site, promoter…?
 +
**how to define these methods?
 +
** when display on JBrowse/GBrowse, do we want to display WBsfxxxxx or methods?
 +
* Gary does a quick literature search to see what other work has been done in the sites described.
 +
**along this line, do we wanna add WBPaper00002925 to WBsf from WBPaper00002011? mean, associate features with two paper, both mentioned these features?
 +
*** The Feature objects are used to describe 'real', functional regions of the genome in as much detail as possible. Each paper that provides evidence for that region being 'real' should be added as evidence for the Feature. The Primary object we are trying to describe here is the region of the genome, not the papers. (I may have missed the point you were making - Gary).
 +
*** agree with Gary (unless I have also missed the point!). All relevant papers should be added. There is a loose convention in Allele curation that the paper listed under Evidence (which can only have one value) is the "primary" paper and the ones listed under Reference (including the primary) are all papers which describe or discuss the object as well. Also individual Evidence can be added to tags. Maybe we should look to extend this in the Feature model.

'''Duplicated Features'''
 +
The following are a set of duplicated regulatory Features. I (Gary) am probably the main culprit in not checking to see if there is a pre-existing Feature.
 +
How can we avoid this in future?
 +
* The list of duplicated Features has been moved to the Discussion page.

Headline text

Topics

  • Display of Sequence Features on the website
    • See github ticket 2867 https://github.com/WormBase/website/issues/2867#issuecomment-48041365
    • And Transcription factors and Gene_product binds.
    • in the expression section on the gene page highlight the objects that are Sequence feature related. Add in the table a type called cis-regulatory-element?
    • add a sequence feature table in sequence widget to display all features related to the gene
    • in cytoscape display, sequence feature as an entity node
  • Stream out working flow
    • How can we automatically identify Sequence Feature papers.
    • How do papers come in now? SVM? Textpresso string matches?
  • Improving data flow
    • How can we make the data immediately available to all curators?
      • Add Paper and Public_name fields to the Features in the Nameserver?
      • geneace is available for download updated every day - a copy is taken by Caltech.
        • still need WBsf object details in order to relate/curate regulation/expression/construct objects


  • Sample papers curation
    • Prepare a paper list from each person
  • assign meaningful names to the public_name field, e.g. 'distal enhancer 1' instead of 'DE1'
    • gw3 - I disagree with this. We should use the name that is used to describe the region in the paper, rather than making up our own names. I have had to go back and re-annotate regions after Xiaodong found problems with my stuff several months after I had originally done it and I really needed to be able to unambiguously identify which region the paper was talking about by using the Public_name field and matching this up to the name of the region in the paper. Users may well need to do this as well if they are reading the paper and looking at the Features marking up the regions.
    • dr - ok sounds good to me Gary

Practical Issues

  • Gary and I are staying at the Ramada - 800 Morrissey Boulevard, Freeport St, Boston, MA 02122 US
  • We arrive in Boston on Saturday evening and fly home on Wednesday night.
  • What time shall we meet on Monday morning and where do we go?
    • I (Xiaodong) can pick up you guys at Harvard square T station (red-line, info center on the square) at say 9:30 am. We can walk to my office.
  • Can you confirm that we have office space with internet access? I will bring my Macbook. Hopefully I can tunnel into my Sanger working space.
    • Enough office space for sure. Internet access through Harvard guest. They won't allow you to access other ways.
  • Thanks Xiaodong, I'm bringing my chromebook - Gary

Pre-Jamboree prep

  • Suggestions for work
    • Curate some (5? 10?) papers from our lists and collate data as follows
      • How long did each paper take to curate
      • How many new objects did you add to WormBase
      • Where in the paper was the information (e.g. supplementary data, figure legends, within text)
      • Did you need to contact the author for more information
      • Did you come across data for other curators
        • gw3 - I don't know in detail what data other curators require. It would be useful to know this so I can summarise data for others.

The Jamboree 15-17th Sept 2014

  • Suggestions for work
    • Discuss result from above
    • Work through some papers which have already been curated and have different data types (e.g. promoter and gene regulation) to identify best curation practices.
    • browsing capabilities through WormMine?
    • Should we put the list of papers in the Caltech curation status form


Matters Arising

  • things noted - not necessarily to do with the topic in hand
    • There are many duplicates of Interaction objects in geneace, with or without two leading digits. Sometimes there is only the shorter form.
    • The Features WBsf919641 and WBsf919607 are at the same position. Both are DAF-3 binding sites. WBsf919641 has Method "binding_site", WBsf919607 has Method "TF_binding_site" which I think is more correct as DAF-3 is a TF. WBsf919641 used the paper WBPaper00004526, WBsf919607 used the paper WBPaper00003384. WBsf919641 is associated with WBGene00202278, WBsf919607 is associated with WBGene00003514 (myo-2). The paper WBPaper00004526 appears to about a PEB-1 binding site, not a DAF-3 site. I made the Feature WBsf919609 for the PEB-1 site based on WBPaper00004526 in the last round of curation. Something not right here???
      • Follow-up from Mary Ann. I agree Method for WBsf919641 should be TF_binding_site. Associated_with_gene should be updated myo-2 (this is an error). So term is not right either. These then become duplicate entries.
      • Resolved: WBsf919641 merged into WBsf919607 - GW
    • The Features WBsf019227 and WBsf038813 and in the same position, but opposite strands. They both are for a LAG-1 binding site associated with gene lin-11. One from paper: WBPaper00005357, other from WBPaper00032298. WBsf019227 needs to be retired and merged into WBsf038813.
      • Follow-up from Mary Ann. We have no merged_into tag structure in Feature. We have History tag and could add a Comment there.
        • We have a merged_into tag structure in Feature. - GW
      • Resolved: WBsf019227 merged into WBsf038813 - GW
    • WBsf038819 has a Method of 'regulatory_region', but the Public_name and Description describes it as an Enhancer. Which is it?
      • Fixed by Mary Ann. Changed Method to enhancer.
    • WBsf919669 is an Enhancer, but it has a tag for a Transcription_factor WBTranscriptionFactor000101. It is far too large to be a binding site for a transcription fact. I think this tag should be removed.
      • Follow-up from Mary Ann. lag-1 does bind somewhere in this region, but the paper does not allow me to specify exactly where. Q. Should we curate these then? I think we should, but should maybe add suitable Remarks.
    • 393 out of the 500 TF_binding_site Features have an incorrect SO_term tag. It should be set to: SO:0000235
      • Follow-up by Mary Ann. This seems really high. I wonder whether TF_binding_site was not a recognised SO term when some of these were curated, especially the older ones. This (and other consistency checks) should be added to a script we can run.
      • Resolved: all TF_binding_sites with SO_term SO:0000409 changed to SO:0000235 - GW
    • 10 Features with Method = "TF_binding_site" are lacking a Transcription_factor tag.
      • Follow-up by Mary Ann. Maybe it's not clear in the paper what the TF is? Something to add to consistency check.
      • Resolved: the MEC-3/UNC-86 heterodimer has been added - GW
  • how many 'Method's for feature? enhancer, regulatory_region, TF_biding_site, promoter…?
    • how to define these methods?
    • when display on JBrowse/GBrowse, do we want to display WBsfxxxxx or methods?
  • Gary does a quick literature search to see what other work has been done in the sites described.
    • along this line, do we wanna add WBPaper00002925 to WBsf from WBPaper00002011? mean, associate features with two paper, both mentioned these features?
      • The Feature objects are used to describe 'real', functional regions of the genome in as much detail as possible. Each paper that provides evidence for that region being 'real' should be added as evidence for the Feature. The Primary object we are trying to describe here is the region of the genome, not the papers. (I may have missed the point you were making - Gary).
      • agree with Gary (unless I have also missed the point!). All relevant papers should be added. There is a loose convention in Allele curation that the paper listed under Evidence (which can only have one value) is the "primary" paper and the ones listed under Reference (including the primary) are all papers which describe or discuss the object as well. Also individual Evidence can be added to tags. Maybe we should look to extend this in the Feature model.

Duplicated Features The following are a set of duplicated regulatory Features. I (Gary) am probably the main culprit in not checking to see if there is a pre-existing Feature. How can we avoid this in future?

  • The list of duplicated Features has been moved to the Discussion page.

Papers to curate

  • I have taken the Sequence Feature Papers from RT and assigned the four of us 10 papers each.
  • Just in case there is any paper here that has already been curated for Interaction, I've added the number of Interaction objects linked to by the paper. If this is not helpful, feel free to remove it.

                mk125-132 (4331-4474) is sufficient to drive strong expression in vulC and vulD. Expr11838 add feature and generate construct

                mk84-148 contains two regions that together confer strong expression in VulE and VulF. Expr11839 add feature and generate construct

                mk50-51 (1052-1438) is sufficient to confer AC, vulE, and vulA expression, as well as uterine cell expression. Expr11840 add feature and generate construct.

                mk96-144 (2290-2522) expresses in AC in all animals observed. Expr11841 add feature and generate construct.

                mk66-67 (4434-4997) is sufficient to confer vulval cell expression. Expr11842 add feature and generate construct.

                mk135-134 (2412-3419) is sufficient to confer vulval cell expression. N.B.: in text is mk135-134 in fig 4C seems mk135-143. Expr11843 add feature and generate construct.

                Location of information: The nucleotide sequences for pertinent regions are shown in Figs. 5, 6, and 7 of the Supplemental Material.
                Comment: It would be good that a sequence curator will read the paper unbiased-w/o checking what I have curated for expression and see if we could identify the same regions

                Comments (XW): curated one new cis-regulation object with Gary's WBsfs

WBPaper00005044 Gary Interaction: 20
                Time: 3 hours
                New objects: made ire-1 binding site Feature (WBsf977530)
                Location of information: body of this paper and WBPaper00005036
                Other curator data: IRE-1 is a stress-activated endonuclease resident in the ER that is conserved in all known eukaryotes. IRE-1 mediated unconventional splicing of an intron from xbp-1 mRNA controls expression of the encoded transcription factor and is required for upregulation of most UPR target genes.

                New objects: Made WBsf977532, WBsf977533 M-2 motif/daf-12 binding sites for ceh-22
                New objects: Made WBsf977534, WBsf977535 M-2 motif/daf-12 binding sites for myo-2
                Location of information: body of this paper and Figure Supplemental 3
                Other curator data: "We conclude that regulation of myo-2 and ceh-22 during dauer development depends critically on the M-2 motif."
                Comments: lots of hypothetical binding sites for daf-12 in 90-odd genes, but these have not been experimentally confirmed.
