Re: [galaxy-user] Contents of a SAM file

2013-11-07 Thread Mohammad Heydarian
Hi Benjy, To extract unmapped reads from a SAM file in Galaxy, you can use 'Filter SAM' ('NGS: SAM Tools' - 'Filter SAM'). Add a 'flag' and use the 'The read is unmapped' type, then set the state for this flag to 'Yes'. This should return a SAM file with your unmapped reads. Cheers, Mo

Re: [galaxy-user] Exceptionally high RPKM values of miRNA and other short genes in Cuffdiff's output

2013-07-18 Thread Mohammad Heydarian
Hi Thanh, This is due to Cuffdiff correcting for the size of smaller transcripts, the authors call it the effective length correction. It is supposed to correct the loss of shorter transcripts upon size selection in creating your RNA-seq library. The default setting on Galaxy is to use the

We are having the exact same issue, on the main server and our (recent) cloud instances. Were some of the hidden Cuffdiff parameters modified since fall 2012? Cheers, Mo Heydarian On Mar 13, 2013 11:02 AM, Jenna Smith jes...@case.edu wrote: Hi, I'll preface my concern by saying that I'm a

[galaxy-user] Counting intervals in one file overlapping intervals in another file - what are the hidden settings?

2012-08-16 Thread Mohammad Heydarian
Hi, I am using the Count intervals in one file overlapping intervals in another file tool (part of the bedTools package) to assess the number of RNA-seq reads that map back to a specific region. (I am using this on the Galaxy test server). I am finding that this tool returns many more reads than

[galaxy-user] Generating pile-up files without spliced (intronic) regions.

2012-07-15 Thread Mohammad Heydarian
Hello, Is there a way to generate a pile-up from a BAM file in SAMtools without including spliced (intronic) regions? Alternatively, is there a way to split spliced reads in a BAM file? Thanks in advance! Cheers, Mo Heydarian ___ The
