1st April 2009

This work has been on hold for a while as we were waiting for more sophisticated filtering in OBO-Edit to let all editor edit the file while doing normal live file editing. However Chris has asked that we push on without the filtering for a while.


Loaded the files in OE2 and found some file problems. The UnionTerm stanzas were a bit messed up, but were fixed by adding a Typedef for the the union_of relationship, and removing the top term.

Other file errors found and fixed:

Two entire taxa had gone missing from the taxon slim, and we had also lost a union_of term from the UnionTerms file. I do not know how that happened but I have replaced them.

Midori had added a new only_in_taxon link to a union_of term that did not exist. I have made the union_of stanza and added it to the file. I should check with Midori that she knows all the ins and outs of the editing of these files. I did not know she had started.

I have recommitted the edited source files and also saved out and recommitted the all_files_mid_edit.obo file. I did not make any edits so the perl scripts do not need to be run.

Fixed this misformed tag 'name: synonym: "synonym: "synonym: "'in both edit file and source.

Set up WinXP laptop to run the perl scripts to generate the tab delimited file that the users need to act on these links.

TODO: There are a bunch of terms that currently have two only_in_taxon links and they mess up the converstion to tab-delimited. Need to resolve these relationships. Have deleted them from the file for now. This is the list:

GO:0048494	chromatophore ribulose bisphosphate carboxylase complex
GO:0030075	plasma membrane-derived thylakoid
GO:0030094	plasma membrane-derived photosystem I
GO:0030096	plasma membrane-derived thylakoid photosystem II
GO:0031676	plasma membrane-derived thylakoid membrane
GO:0031979	plasma membrane-derived thylakoid lumen
GO:0048493	plasma membrane-derived thylakoid ribulose bisphosphate carboxylase complex
GO:0009521	photosystem
GO:0030077	plasma membrane light-harvesting complex
GO:0042716	chromatophore
GO:0009760	C4 photosynthesis
GO:0009761	CAM photosynthesis
GO:0016168	chlorophyll binding
GO:0030093	chloroplast photosystem I
GO:0030095	chloroplast photosystem II
GO:0030089	phycobilisome

I am wondering what the violations.txt file is in cvs. There is a readme but it is a dead end when you follow the urls.

9th April 2009

Looked through the rest of Michelle's taxon spreadsheet and sent a few questions to her before doing the final edits:

Oh that's good to know. So for now I should make these prokaryote,
but later we might like to make child terms then?

Good to know. So I'll leave these as Bacterial for now and we can add Archaeal terms later.

Yes that would be fine. Which ones would you like me to add? If you
put a column in the attached spreadsheet and write the names in I can do the edits.

27th/28th April

The prokaryotic terms are now finished and a list of questions has been sent to SGD for the fungal terms.

A plan has been formed to finished the sensu terms and release the file in time to submit a paper to this conference:

IEEE International Conference
on Bioinformatics and Biomedicine (BIBM09)
Washington DC, USA, Nov. 1-4, 2009
Electronic submission of full papers: July 10, 2009
