svtools copynumber:Can't find directory 'bin_1000'.

[pingxinxing]

Hello, I want to ask you a question. I provided my correct bin value, bin=200. Why is this error? "Can't find directory 'bin_1000'." Also, is the root file needed in this step the root file generated by CNVnator after executing his or the root asking price generated by CNVnator's last call cnv?
