Hi, I get an error as follow:

1, my command: ~/miniconda3/envs/OSCC/bin/methplotlib -m /NAS/wg_xialin/pancancer/raw_data/oral/fast5/yyl.T/yyl.T_methy.tsv /NAS/wg_hl/pancancer/OSCC/Methylation/f5c_meth/OSCC3/OSCC3.meth_cov10_freq.format.tsv -w chr1:99678000-99688500 -n calls frequencies --simplify

error: Input file /NAS/wg_hl/pancancer/OSCC/Methylation/f5c_meth/OSCC3/OSCC3.meth_cov10_freq.format.tsv not recognized!

The above exception was the direct cause of the following exception:

2, I have modified the command to the following: ~/miniconda3/envs/OSCC/bin/methplotlib -m /NAS/wg_xialin/pancancer/raw_data/oral/fast5/yyl.T/yyl.T_methy.tsv /NAS/wg_hl/pancancer/OSCC/Methylation/f5c_meth/OSCC3/OSCC3.meth_cov10_freq.format.tsv -w 1:99678000-99688500 -n calls frequencies --simplify

but no content in the output image. May I ask what the reason is and how can I solve it. Thanks.

Hi,

Thank you for reporting this. I will look into this. I don't have an immediate explanation, and due to my parental leave it may take longer to follow up on this.

Cheers, Wouter
