hi all
15:08:13 [egonw]
mscottm: today start discussing remaining issues for expression rdf document
15:08:20 [egonw]
there has been a publication already
15:08:29 [egonw]
link follows:

15:12:43 [egonw]
that GDoc discusses using RDF for gene expression
15:13:03 [egonw]
biggest missing pieces
15:13:15 [egonw]
a general tool that converts MageTab into RDF
15:13:40 [egonw]
take interesting gene list and convert into RDF, including exp details, etc
15:13:46 [ericP]
hi all, i'm pushing to get some stuff presentable for an hl7 meeting.
15:14:18 [ericP]
s/hi all, i'm pushing to get some stuff presentable for an hl7 meeting.//
15:15:30 [egonw]
mscottm: I did not full get that last major point

15:17:44 [egonw]
jim: general framework for converting MageTAB into RDF...

15:25:09 [egonw]
.ttl did not work for me either
15:26:07 [pekkoh]
Hello. I know i am a bit new at this (Pekka Kohonen from Karolinska Institutet) but are you aware of the ISA-TAB and the ISA2RDF tools?
15:27:12 [pekkoh]
This is a ToxBank/SEURAT-1 consortium project (Egon knows). Can convert automatically mage2ISA and then ISA2RDF.
15:27:32 [mscottm]
Pekka - Jim mentioned "ISA" a few minutes ago as a way to reference assays, IIR
15:27:43 [michael]
hi pekkoh, yes we are, but we've started with MAGE-TAB, ISA-TAB would be similar
15:29:03 [pekkoh]
OK.
15:29:24 [JimMcCusker]
http://aquarius.tw.rpi.edu/projects/lobi/P-GSE17089-4.html
15:29:35 [egonw]
JimMcCusker talks the telcon through some of the patterns
15:29:53 [egonw]
mscottm noted that the .ttl link did not work, may have been misrepresented, said JimMcCusker
15:33:27 [mscottm]
bnode used to represent implicit input to the activity in the provenance for the protocol
15:34:53 [egonw]
OBI is used to refer to general processes...
15:35:11 [JimMcCusker]
http://aquarius.tw.rpi.edu/projects/lobi/E-GEOD-17089.html
15:35:16 [egonw]
protocols realize some process (more than one?), e.g. http://aquarius.tw.rpi.edu/projects/lobi/P-GSE17089-4.html
15:36:12 [egonw]
and investigation (:investigation, prov:Activity) has protocol realizations as parts (has_part)
15:36:57 [egonw]
study designs are represented using EFO: http://aquarius.tw.rpi.edu/projects/lobi/E-GEOD-17089/studyDesign.html
15:38:28 [egonw]
egonw: is there an ordering of has_part linked protocols...
15:38:42 [egonw]
JimMcCusker: that order is implied by input and output of protocols
15:38:53 [egonw]
ok, thanx :)
15:40:56 [egonw]
JimMcCusker: prov:used is used to refer to the samples, materials, etc... e.g. http://purl.org/twc/arrayexpress/E-GEOD-17089/sourcename/GSM427343_1
15:41:09 [egonw]
this happens to be a cell line, A375P
15:41:39 [egonw]
here modeled as a "material entity" (BFO_0000040)
15:43:06 [JimMcCusker]
http://aquarius.tw.rpi.edu/projects/lobi/P-GSE17089-1.html
15:45:35 [egonw]
primary use case: discoverability, reuseability of results
15:45:55 [egonw]
JimMcCusker has visualizations, e.g. showing how methods changed over time
15:47:31 [egonw]
? suggests the example of a refuted cancer study...
15:47:43 [egonw]
which could be looked up in microarray dbs
15:52:16 [egonw]
practical problems in the data analysis which may have been tracked with a systematic approach
15:52:37 [egonw]
mscottm asks what is missing in JimMcCusker's work
15:53:21 [egonw]
JimMcCusker: one problem is samples from human, which are not instantiations of humans
15:53:33 [egonw]
so, tricky to pick the right OBI/... predicate
15:53:51 [michael]
reanalisis of duke gene expression experiment: http://www.economist.com/node/21528593
15:53:58 [mscottm]
Scott confirms understanding of use case application: Find studies that make use of same assay, protocol, enzyme, analysis, etc.
15:54:57 [egonw]
that is: how to encode "is a sample originating from human"
15:55:33 [egonw]
closest now is "has characteristic"
15:55:59 [egonw]
btw, I need to leave in 4 minutes...
15:56:10 [mscottm]
tx for the warning
15:56:11 [egonw]
if we are not done by then, can someone scribe the remaining few minutes?
15:56:15 [mscottm]
sure
15:57:26 [Helena]
<michael> reanalisis of duke gene expression experiment: http://www.economist.com/node/21528593 -> michael: I know Keith Baggerly and Kevin Coombes (the statistians who uncovered the fraud) - they spent at least 3 years attempting to reanalize the data
15:58:57 [JimMcCusker]
http://aquarius.tw.rpi.edu/projects/lobi/E-GEOD-17275/sourcename/GSM429727_2.html
15:59:36 [egonw]
ok, I have to leave
15:59:43 [egonw]
I note that our group does this pipeline:
15:59:49 [egonw]
http://arrayanalysis.org/
16:00:06 [egonw]
and will see if people here can be interested in magetab2rdf
16:00:09 [egonw]
cheers!
16:01:49 [mscottm]
tx egon!
16:05:16 [JimMcCusker]

16:05:56 [mscottm]
There's a characteristic for homo sapiens for the sample (in the URL Jim just posted above)
16:12:19 [michael]
michael has left #hcls
16:12:55 [egombocz]
I've to leave, but very good discussions!
16:13:17 [mscottm]
tried Zooma but it doesn't get you all the way to the URI for the ontology class.

scott, I think it's 'world visible' instead of public

16:23:03 [Helena]
tks for logging
16:23:13 [mscottm]
thanks Lena!
