Reducing memory consumption #6

Open cassisnaro opened 3 years ago

cassisnaro commented 3 years ago

Hi, I am trying to run the preprocessing step of nebula on a BAM with long reads, in order to later on call it on short read BAMs. However, I am running out of memory: with the entire BED file, 450GB of RAM was not enough. If I take only a fraction of the BED it works, but I am not sure how to then do the merge. Will Nebula consider it as multiple samples? Thanks

Hi,

Nebula is not meant to be used and has not been tested with long read (PB or ONT) BAM files with high-error rates. This may result in excessive amounts of kmers being extracted.
