[STAR] How to clear memory after lost –genomeLoad

Hi all,

I’m regularly using STAR and happen to play with the argument --genomeLoad.
My problem is that I think a genome index is still loaded in memory but I can’t find it (I tried to --genomeLoad Remove all the indexes I could find and none of them cleared the memory).
I’m not sure how it happened though. I ran zUMIs that failed and I think it’s related (it’s using STAR to map). It’s also possible that I changed some directory location that contained an index.

Anyway, is there a magical way to remove all STAR indexes in memory whatever their path? Are there other tips to clear the memory in such situation (other than rebooting the server…)?

Cheers,
Mathieu
