Paul 2011/3/31 lishiyong <lishiyong@genomics.org.cn> Hi: I gain the SOLiD sequencing data.I used bowtie to map human genome then I sort the sam file .I used cuffinks to calculate FPKM with the sam file ,human gtf file .it gives 0 FPKM values and this is for all genes .what's the reason? (1) bowtie -C human_hg18_color -f F3.csfasta -Q F3_QV.qual -v 2 -k 100 -p 6 --mapq --sam test.sam (2) samtools view -uS test.sam 2>/dev/null | samtools sort -m 2000000000 - test.bam (3) cufflinks -G refGene_hg18.gtf test.bam.bam 2011-03-31 lishiyong ___________________________________________________________ The Galaxy User list should be used for the discussion of Galaxy analysis and other features on the public server at usegalaxy.org.
