GO Managers, Weds. June 4th, 2008 8 AM PDT, 9 AM MDT, 10 AM CDT, 11 AM EDT, 4 PM BST
Action items from last meeting
Managers (especially call chair): Meeting agenda should be available on Monday (48 hours in advance)
Managers: Post progress reports on Wiki with links back and forth (e.g. from call agenda to report); refer to wiki during call
Managers (especially call chair): ‘Hot topics and Concerns’ should be at the top of the agenda
Managers (especially call chair): The chair is empowered to manage the call; "Chair trumps PI".
Managers: Digressions become an action item, not to consume the time of the manager’s meeting
All: GO-paid staff should check with PIs before writing papers or going to meetings.
GO-top: Discuss meeting frequency, who should come, etc.
GO-top: Discuss Jane’s letter about review for Human Genetics
Jen:Put together bigger picture of function – process task (Jen is on holiday this week but will do this for the next meeting.)
Hot Topics and Concerns
- Montreal GO Meeting (Pascale):
Found a nice place for Oct 21-23 (21, 22: GOC; 23: GO SAB). We could extend 1-2 days for an annotation meeting? I don't need to confirm this until some time in July but it may be easier to reserve dates now, even if we cancel later.
Report on current status by Jennifer Deegan.
The biological process "photosynthetic electron transport" is to be connected to all its consistuent molecular functions in the function ontology. http://www.life.uiuc.edu/govindjee/photoweb/art/electron-transfer.jpg
- The same process has different constituent functions when it happens in different taxonomic groups.
- For example photosynthesis in chloroplast-containing organisms and cyanobacteria is a bit different from photosynthesis in other photosynthetic organisms (e.g. purple bacteria).
As I understand it Chris has an idea of how we could manage still to make the mf-bp links without putting taxon information into the actual ontology file. I think his idea is to make a separate file that would contain the mf-bp links and the taxon constraint information. I guess it would be something like:
|photosynthetic electron transport||has_part||electron transport, transferring from P700 (photosystem I) to Ferrodoxin Sulphur protein||in organisms with chloroplasts (Viridiplantae) and cyanobacteria|
|photosynthetic electron transport||has_part||electron transport, transferring from P680 (photosystem II) to plastoquinone||in organisms with chloroplasts (Viridiplantae) and cyanobacteria|
|photosynthetic electron transport||has_part||electron transport, transferring from cytochrome complex to plastocyanin||in organisms with chloroplasts (Viridiplantae) and cyanobacteria|
|photosynthetic electron transport||has_part||electron transport, transferring from plastoquinone to cytochrome b6/f||in organisms with chloroplasts (Viridiplantae) and cyanobacteria|
|photosynthetic electron transport||has_part||electron transport, transferring from plastocyanin to photosystem I||in organisms with chloroplasts (Viridiplantae) and cyanobacteria|
His alternative idea is to subclass the process term using non-taxon differentia as we do now with the old sensu terms. For example "chloroplast-based photosynthetic electron transport" however, I can't see how this could be done across the board without making really unusable clunky names. This does not seem a viable option to me.
I would like to hear people's views generally. The scientists that I have been working with are concerned, as am I, that this project is just infeasible. We would like to discuss the issues frankly before we use any more time on the pilot project.
- Can we make these kinds of generalization when scientists have not checked all taxonomic subgroups?
- Are we prepared to take on the amount of work that would be involved in situations where there may be many many different variations in different taxonomic groupings.
- Are we instead proposing only to cover a small number of well known and researched species, and are we sure that the information is fully available in those cases?
or as Chris says:
- how much time should we spend on each process term in GO?
- how important is it to get each individual function step as the process is instantiated in a given cell? i.e. are gaps a problem
- how important is it to get broad coverage across different organisms or variations of a process? i.e are "representatives" enough?
It may be that we are just not able to make the bp-mf links because of the complexity involved, but I think we have now reached a place where it makes sense to stop and discuss it before using more time on the pilot project. All thoughts much appreciated.
