Hi all, 

 

Quick question, I was wondering if it possible to use directly, the output of a DEXSeq analysis and pass it in to analysis for isoformswitchanalyzeR? I have looked but cant find any information on this....

 

If so, which step can it be picked up from in the vignette?

 

Many thanks!

Nope. But what you can do is use IsoformSwitchAnalyzeR to run DEXSeq - acutally DEXSeq is the default statistical engine (via the isoformSwitchTestDEXSeq() function) so you can just start from the top of the vignette.

Please note that if you have >2 conditions IsoformSwitchAnalyzeR will do all pariwise comparisons (as opposed to DEXSeq which performing a single ANOVA-style test). 

Let me know if you have more questions :-)

Cheers

Kristoffer

Thank you so much for the quick response! I guess one quick follow up question... As im not too familiar with the command line alignment tools, can a feature counts output (counts over exons) be passed to IsoformSwitchAnalyzeR. Would that suffice as a counts table?

 

Thanks again!

Unfortunatly not - you need transcript expression. That can be done with the tools discussed in the vignette here.
