Hi Arielle,
This is a strange issue that I've not seen before. In general this would seem to mean that no LSVs were detected. Could you post the output of the $ psi-coverage command you ran? It should say some log at the end like:
Assessing coverage for Events[227 events, 637 connections] on SpliceGraph[11 contigs, 20 genes, 432/114/562 exons/introns/junctions]
Saving PsiCoverage[637] for 1 experiments [workshop_Adr3] to .psicov
It's also possible that you mistakenly input the annotation splicegraph file to the psicoverage command, instead of the splicegraph that was build as a result of the majiq-v3 build command. This would cause there to be no events detected.
If you see zeros in those log print lines above, that's likely what happened, otherwise, I might need to investigate deeper into your dataset.
Let me know what you find from the log.
Thanks,
-San
