calculating TPM values the tpm_table.py script

[mars188]

Hello,

I have generated all the required files and now want to calculate the TPM values of my metagenomic samples. When I run the script, it does produce the output file but it contains ONLY ONE column with gene ids that's it. The output file doesn't contain the second column with TPM values. Here is my script.

tpm_table.py -n A_case -c A_case.count -i <(echo -e "A_case\t100") -l A_case.genelengths > A_case.tpm

Please help me to identify if I made any mistake? Thanks
