TypeError: can only concatenate str (not "collections.defaultdict") to str

[Canglan111]

I used the command:
python3 /PAPipe/bin/main.py -P./main_param.txt -I./main_input.txt -A./main_sample.txt.
The error message is as follows:
-----------------Start-----------------
------------Postprocessing-------------
Traceback (most recent call last):
File "/PAPipe/bin/main.py", line 99, in
Postprocessing.main_pipe(args, dict_param, index)
File "/PAPipe/bin/Postprocessing.py", line 298, in main_pipe
post_param = Param.Postprocessing(args.out, dict_param)
File "/PAPipe/bin/Param.py", line 85, in Postprocessing
O_post_param.write("<" + dict_param["VariantCalling"]["VCF_prefix"] + ">\n")
TypeError: can only concatenate str (not "collections.defaultdict") to str
Thank you for your advice and help.

Any update on this? Is this repo no longer maintained?

Hi, I apologize for missing this issue earlier—it must have slipped through.
The repository is still maintained, and I'm currently looking into it.
I'll update you soon. Thanks for your patience.

Hello, I have also run into the error as well. For context my input file in a joint genotype vcf file that was called using Gatk4.

A same error appeared (starting from a vcf.gz file). Thank you for your advice and help.
