I install cnvkit recently and try to fun it, my command is:

python2.7 /Software/cnvkit/cnvkit.py batch /Projects/P46-tumor.sorted.bam --normal /Projects/P46-blood.sorted.bam \ --processes 0 --targets /APP/Panel2.bed --fasta /Data/HG19/hg19.fa \ --split --access /Software/cnvkit/data/access-5k-mappable.hg19.bed \ --output-reference /Work/P46/varscan0/tumor_blood.cnn --output-dir /Work/diagnosis2/P46/varscan0/

Then several minutes later, it show me following reports and I don't know why. Could any one help me? Thanks very much!

The error as I see is because the output.cnn is not found. Try creating the same in the working directory. I have modified the command, paste it directly and check if the error appears. I have also removed the process argument as it was 0.

python2.7 /Software/cnvkit/cnvkit.py batch /Projects/P46-tumor.sorted.bam --normal /Projects/P46-blood.sorted.bam --targets /APP/Panel2.bed --fasta /Data/HG19/hg19.fa --split --access /Software/cnvkit/data/access-5k-mappable.hg19.bed --output-reference tumor_blood.cnn --output-dir /Work/diagnosis2/P46/varscan0/

Hope this works.
