unexpected error during read extraction process using nanodisco preprocess

[tweedle828]

Hi,

I'm using nanodisco to analyze the WGA dataset (https://www.ncbi.nlm.nih.gov/biosample/SAMEA111521248). I used the following command and I don't know why I got following error there...

Thanks for your help.

nanodisco preprocess -p 8 -f E1_WGA_even_coverage_fast5 -s E1_WGA_even_coverage_fast5 -o ../analysis/E1_WGA_even_coverage_fast5 -r ../reference/SC452.fasta

nanodisco preprocess -p 8 -f B2_WGA -s B2_WGA -o ../analysis/B2_WGA -r ../reference/SC419.fasta

Hello @tweedle828,

Were those fast5 basecalled? I've wrote a simple example for nanodisco processing here.

Please let me know if this help.
