How to interprete "NAs" in the psi.gz file?

[SiyiWanggou]

Hi, Timbitz: I'm using "Whippet" to compare alternative splicing of different samples from RNAseq data. The idea to identify AS events from event-level is really brilliant. When I finished the Whippet analysis, I got a psi.gz file from each sample. In the file, there are a lot of "NA"s. How to interpret these "NA"s? Is it "0" or can just be filtered out in the following analysis? On the other hand, I found you used Mann-Whitney U test to compare the difference between samples in the published paper, but the Whippet package provides whippet-delta.jl for sample comparison. What's the differences between these two methods? Is Mann-Whitney U test integrated in whippet-delta.jl? Or, should should we use Mann-Whitney U test to find differences independently? Thanks

Hi, I am resuming this old issue since I had the same problem in interpreting NAs in the .psi output, do you have any suggestion about this? Thank you
