Error when running CHESS on JUICER HIC files

[rkuzya]

Hello,

I would highly appreciate your help with the issues I have been facing when trying to run CHESS on my HIC files.

I have installed CHESS (0.3.6) and successfully tested it on the data provided in the repository.
All output files and plots (for CHESS data sets) have been generated by following the instructions provided in the online manual and the jupyter notebook.

Unfortunately, the tool has crashed when new data (Juicer HIC files) had been provided.
Here is the CHESS error message for the command I have used:

chess sim -p 6 CTRL_1.hic ./Tip5_1.hic mm10_chr2_3mb_win_100kb_step.bed ./chr2.result

I have been working with MM10 genome and the hic files have been produced with Juicer.
Here is the validation of the HIC files done with the Juicer tools:

Any help on the current issue would be highly appreciated.
With best regards.

Please have a look here, to see if it solves your issue: #36

Thank you very much for your help!
It worked.
I got the output file.
As in issue #36, I also got a message:
Could not compute similarity for 68 region pairs. This can be due to faulty coordinates, too small region sizes or too many unmappable bins

But it is ok.
I will proceed with further analysis as indicated in the manual and contact you when having some questions.

Best.
Ross
