This problem is being faced by my friend he posted it on biostar but he was not able to do the same in seqanswers!! -
Cuffdiff problem output!!!
i have some problem related to cuffidiff output, i used this command for replicates:
cuffdiff -o diff_out -b <genome.fa> -p 10 -L CT,SS --total-hits-norm -u cuffmerge_experiment/merged.gtf tophat_exp/exp1/accepted_hits.bam,tophat_exp1/exp2/accepted_hits.bam tophat_exp/exp3/accepted_hits.bam,tophat_exp/exp4/accepted_hits.bam
in my output file i found gene column is empty:
TCONS_00000001 XLOC_000001 - C11044824:403-1007 CT SS OK 4.25634 4.05292 -0.0706522 0.148488 0.881958 0.999985 no

i cant understand how can be its possible, if any one have suggestion please guide me.
upto cuffmerge i found gene in my file like this:

This year’s Advances in Genome Biology and Technology (AGBT) General Meeting commemorated the 25th anniversary of the event at its original venue on Marco Island, Florida. While this year’s event didn’t include high-profile musical performances, the industry announcements and cutting-edge research still drew the attention of leading scientists.
The Headliner
The biggest announcement was Roche stepping back into the sequencing platform market. In the years since...03-03-2025, 01:39 PM -
The human gut contains trillions of microorganisms that impact digestion, immune functions, and overall health1. Despite major breakthroughs, we’re only beginning to understand the full extent of the microbiome’s influence on health and disease. Advances in next-generation sequencing and spatial biology have opened new windows into this complex environment, yet many questions remain. This article highlights two recent studies exploring how diet influences microbial...02-24-2025, 06:31 AM
