Curious, I see

cellbender_removebackground

can run on GPU via

--cuda

. To set this in nf-core/scrnaseq, all I have to do is include

-profile gpu

when calling Nextflow?

yep, see https://github.com/nf-core/scrnaseq/blob/master/conf/base.config#L54 and https://github.com/nf-core/scrnaseq/blob/master/modules/nf-core/cellbender/removebackground/main.nf#L33
