I forgot to mention,
I have many differentially expressed genes and spliceforms, I am not sure to believe them or not!

cuffcompare - wrong results
Hi:
I did following:
cuffcompare -i gtf_out_list -r /UCSC/hg19/Annotation/Genes/genes.gtf
cut -f4 cuffcmp.tracking | sort | uniq -c
40816 =
20 c
As per cuffcompare manual column 5 is listed as code column, however I see codes in column 4.
Also my other MAIN concern is why I have over 40K '=' and very little C and no other codes.
Is something wrong with my cufflinks, cuffmerge and cuffdiff?
I also checked same with individual .tmap files:
cut -f3 cuffcmp.transcripts.gtf.tmap | sort | uniq -c
40868 =
20 c
1 class_code
my refmap file is empty.
Could any one suggest what could be wrong. I have been struggling with this for last 4 months and I think I cant get past of this. I request your help.
Thanks
Adrian

Next-generation sequencing (NGS) and quantitative polymerase chain reaction (qPCR) are essential techniques for investigating the genome, transcriptome, and epigenome. In many cases, choosing the appropriate technique is straightforward, but in others, it can be more challenging to determine the most effective option. A simple distinction is that smaller, more focused projects are typically better suited for qPCR, while larger, more complex datasets benefit from NGS. However,...-

Non-coding RNAs (ncRNAs) do not code for proteins but play important roles in numerous cellular processes including gene silencing, developmental pathways, and more. There are numerous types including microRNA (miRNA), long ncRNA (lncRNA), circular RNA (circRNA), and more. In this article, we discuss innovative ncRNA research and explore recent technological advancements that improve the study of ncRNAs.
