Micro-C data

[jeff-godwin]

Hello,

I'm using 3d-genome-builder for yeast micro-C data. As mentioned in the example YML files used in the paper, I left the "hicpro_restriction_sites:" blank in the config file. But I'm getting an error -

Error in rule digest_genome:
jobid: 5
input: genome.fasta
output: HiC-Pro/restriction_sites.txt
log: logs/digest_genome.log (check log file(s) for error details)
shell:
/usr/local/bin/HiC-Pro_3.1.0/bin/utils/digest_genome.py -r None -o HiC-Pro/restriction_sites.txt genome.fasta >logs/digest_genome.log 2>&1
(one of the commands exited with non-zero exit code; note that snakemake uses bash strict mode!)
Logfile logs/digest_genome.log:

Unable to detect offset for None. Please, use '^' to specify the cutting position, i.e A^GATCT for HindIII digestion.

Could you please give me some pointers to fix this?

Thank you,
Jeff
