[galaxy-user] problem with cuffdiff

2013-09-10 Thread Ianiri, Giuseppe
Hy guys, I am performing some RNA sequencing. I am using a gtf file as a reference annotation for the cufflink - cuffmerge steps. Then when I do the cuffdiff I find something strange. Where there is the gene name, the corresponding values (all of them!) are 0, where there is no gene name there

Hi, I have worked so far on the free web-based version of Galaxy; now I have installed Bio-Linux 7, and there is Galaxy in there as well. However, I cannot access to my data (stored on the web version of Galaxy) using Galaxy on Bio Linux. If it is possible, does anyone know how to do it?

Hello, I performed my mapping using tophat - cufflink - cuffmerge - cuffdiff. With the information I have for my analysis so far, I can reannotate wrong genes, check for correct splicing etc. However, I would like to perform some analysis post-alignment, like for example samples clustering,

Hey guys, I have my Cuffdiff output and I was trying to figure out how to get the data I need. I am interested in the outputs Transcript and Gene differential expressed. Does anyone know how to filter for +/- 2-fold difference in expression levels? Thank you Giuseppe Ianiri, Ph.D. Division of

[galaxy-user] Cuffdiff without gene annotation

2012-11-29 Thread Ianiri, Giuseppe
Hello guys, I went through the RNAseq workflow (I didn't do Cuffmerge) and from the Cuffdiff output gene and transcript differential expression testing I filtered some data. For example, for two samples I got about 400 gene and 900 transcript differential expressed with fold change 2. Since I
