chr_make_reference.sh: line 11: =X: command not found

[kimi-du-bio]

Dear all, Thank you for providing this excellent software! When I use the 1_run_TRF.sh script to create a custom reference panel, I meet the error below: chr_make_reference.sh: line 11: =X: command not found

I think this because of an additional "$" character in line 11 of chr_make_reference.sh, and the following may be right? NONNUM=${NONNUMCHR//,/ }

Best wishes
