Exception in thread "Task submitter" java.lang.NumberFormatException: For input string: "null"

[EnHu359]

I tried to use neoflow by exampledata.But I get an error when I run neoflow_msms.nf
this is my code
./nextflow run ./neoflow-master/neoflow_msms.nf \ --ms /mnt/g/example_data/mgf \ --msms_para_file /mnt/g/example_data/comet_parameter.txt \ --search_engine comet --db ./test/customized_database/neoflow_crc_target_decoy.fasta --out_dir test2 \ --pv_refdb ./test/customized_database/ref.fasta --pv_tol 20 --pv_itol 0.05

then I get the following erros:

N E X T F L O W ~ version 21.10.6 Launching./neoflow-master/neoflow_msms.nf[reverent_watson] - revision: 9f41504eb3 Process multiple MS/MS files.

Hello~ @WLYYYYY, I successed this step this morning.
I add a line 'params.cpu = 0 ' in the neoflow_msms.nf, which looks like the code I show in the image below.

Wish this solution will help you!
