Sorry for bumping this message.
Could any member please share how they are using the isofom diff list from cuffdiff. How are you identifying what exon is differing between two isoforms and how are you visualizing the exonic changes.
thanks again.

What next after cuffDiff - isoforms
Dear Loyal,
thanks for the providing cummeRbund. I am enjoying this package every bit of it.
I have one question when it comes to isoforms.
I see that I have 702 isoforms.
###########################################
CuffGeneSet instance for 669 genes
Slots:
annotation
fpkm
repFpkm
diff
count
isoforms CuffFeatureSet instance of size 701
TSS CuffFeatureSet instance of size 675
CDS CuffFeatureSet instance of size 682
promoters CuffFeatureSet instance of size 669
splicing CuffFeatureSet instance of size 675
relCDS CuffFeatureSet instance of size 669
#############################################
when I visualize them in IGV, for gene especially long genes my eyeballs pain and I get hypnotized by lines, to identify which exons are different, or where exactly the splicing is different between q1 q2.
What should one do given these 701 isoforms:
1. How to get which exons differ between q1 vs. q2
2. How to know if expression difference between these two isoforms.
3. How to visually focus on exons that contributed to isoform and splicing difference.
I tried using plotTracks. I cannot see all samples lined up for an exon difference.
Any help to resolve this issue will be greatly appreciated.
Thanks again.

The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...-
