Hi, @tangerzhang, sorry to disturb you again.
After checking the file according to the instruction in #150, my files look like the same as required, but my plot is still empty. Therefore, I'd like to ask for your help.
(Choose ctg000180_np121212121212 as an example)

The format of bam file for drawing heatmap was generated by mapping reads to contig level assembly as follow:

And my groups.agp file looks like this:

The chrn.list file looks like this:
group1 60941085
group10 28967154
group11 27419351
group12 24016781
group13 22413972

group19 14933825
group2 60637849
group20 14699490
group21 12557559

From the results of above files contents, it fits the requires that the ID of contigs must match with which in agp file and the ID of chromosomes in agp file and in chromosome length file are same.

Can you give me some advice? Thanks a lot!
