Re: [galaxy-dev] cuffdiff output: FPKM value zero

2012-09-10 Thread graham etherington (TSL)
Hi Suzan, The problem here is that there's an absence of data for one of the genes you want to compare, so one can't really assign any significance to that particular gene or transcript. This would require inventing a singificance value where if a gene is highly expressed in one sample, but not mea

[galaxy-dev] cuffdiff output: FPKM value zero

2012-09-07 Thread suzan katie
Hello everyone, I am comparing two samples (control and treated) paired end RNA Seq data. In the cuffdiff output I have noticed that few genes have zero FPKM value in one sample and other sample has significant FPKM value. I want to identify uniquely expressed genes identified only in one sample (

Hello Susan The tool is using the identifier in the "gene_id" attribute from the reference annotation GTF to name the output. This link at the tool manual can help: http://cufflinks.cbcb.umd.edu/howitworks.html#hdif The iGenomes dataset may be what you are looking for. "Shared Data -> Data

Hello, I am new to using Galaxy tools. I am running paired end RNA-Seq data on Galaxy and I want to differential gene expression between control and treated samples I was fine until running TopHat output, I am having problems with cufflinks and cuffdiff output. I ran the cufflinks and cuffdiff t

Hi, I have ran Cuffdiff and got output files: transcript differential expression testing, gene differential expression testing. Could you please tell me how to get the significant differential expression gene and transcript ? Thanks, This e-mail message (inc
