Hi,

When running the tracer summarise function, I get the following error:

Traceback (most recent call last):
  File "/home/sebastiaan/miniconda3/envs/tcr_epi_benchmark/bin/tracer", line 33, in <module>
    sys.exit(load_entry_point('tracer==0.5', 'console_scripts', 'tracer')())

256

It is unclear to me what 256 means in this case? Any idea where I need to make adjustments in the config file?

Have you installed all the dependencies, or are you running from Docker?

256 is the error code for the OS saying it couldn't find the binary it was asked to run. So here Python is telling the OS to run dot, which it can't find so it is causing the 256 error code.

Do you have dot installed?
