[ERROR - MainProcess | High fraction of invalid kmers] #175

Closed wososa closed 3 years ago

wososa commented 3 years ago

Describe the bug After data preparation step (https://nanocompore.rna.rocks/data_preparation/), I ran sampcomp. However, I found a lot of ERRORs.

To Reproduce nanocompore sampcomp \ --file_list1 testrun1_eventalign_collapsed_reads.tsv/out_eventalign_collapse.tsv \ --file_list2 testrun2_eventalign_collapsed_reads.tsv/out_eventalign_collapse.tsv \ --label1 testrun1 \ --label2 testrun2 \ --fasta mouse_transcriptome.fa \ --outpath testrun1_v_testrun2

Expected behavior Shouldn't have errors.

Hi, these errors aren't a real problem, they just mean that certain reads get discarded due to high number of invalid kmers. Does Nanocompore complete?

Dear Nanocompore developer,

Nanocompore has been running for a very long time. The last step has been 5 days. should I wait for it to finish?
