Brandon, > I tried replying to the galaxy userlist but it said its for authorized users only, and i asked for permission but no response yet. You can manage your subscription to galaxy-user here: http://lists.bx.psu.edu/listinfo/galaxy-user/ > I just had one quick question, the output files from of CDS diff, promoters diff and splicing diff from cuffdiff only report have sqrt(JS), teststat, and p value stats? Correct. You can find full details of Cuffdiff's outputs in the manual: http://cufflinks.cbcb.umd.edu/manual.html#cuffdiff_output J.

Brandon, These type of questions--questions about to use Galaxy--are best directed to the galaxy-user list, so I've moved it there. > I saw this thread, though it is older I just want to make sure I did my > analysis after the update. > > http://www.mail-archive.com/galaxy-user@lists.bx.psu.edu/msg00084.html > > You mention having to repeatedly merge cufflinks output for cuffcompare to > generate the combined transcripts.

I do not know the statistical methods used for analysis, but this would be a good question to ask either on seqanswers or on the new tophat-cufflinks mailing list: tophat.cufflinks(a)gmail.com > Lastly, in cuffdiff, the CDS, promoters and splicing analyses didn't seem > to work (datasets 190,191,192). any ideas? > This is because the p_id attribute is not being attached to the combined_transcripts dataset produced by Cuffcompare. This problem is due to your reference file being incorrect -- it should be dataset 81, your reference annotation. Thanks, J.

Re: [galaxy-user] Extract sequences from [gtf file] + [genome FASTA file]

Dinesh, Please send questions such as these to the galaxy-user mailing list (which I've cc'd). You can find the 'Extract Genomic DNA' tool under the 'Fetch Sequences' menu. You may also want to use tool search ('Options -> Show Tool Search'). Thanks, J.

Re: [galaxy-user] how to find out the gene_ID correspond to CUFF ID

(cc'ing galaxy-user) Sorry Jeremy, I'm being a bit dense here - where exactly are these tools in > the tool list - I can't find them... David, Both tools are located within the 'Operate on Genomic Intervals' menu. Also, remember that tool search (Options -> Show Tool Search) is useful for finding a tool. Best, J.

how to find out the gene_ID correspond to CUFF ID
by Ying Zhang 01 Mar '11

01 Mar '11

Dear Everyone: I have got one output file after I run Cufflink which contain gene expression information. However, I found out for each gene_ID, it has the format like, CUFF.1151175, do you have idea of how to find out the offical gene ID correspond to this CUFF ID? Thank you very much!

Hello Vasu, Are you still have problems? Updating to the most current distribution dated Feb 18th would be advised, as a starting point: hg pull -u -r ca0c4ad2bb39 https://bitbucket.org/galaxy/galaxy-central/wiki/Features/DevNewsBriefs Please give this a go and let us know if there continue to be issues with using the save icon on your local instance.
