I am new to Snakemake, I just started using it for my project. I am trying to run a software package that uses Snakemake, however the workflow fails and the problem seems to be caused by windows not being able to locate some files [please see below for the complete error report]. Could someone please give me some ideas of possible solutions? Thank you

CodePudding user response：
From you question I assume you are not developing the software package which uses snakemake but you are only using it.
You might be running into an issue where the paths snakemake internally creates are to long for windows and exceed the maximum path length of 260 characters which Windows uses by default.
The very long line with the long paths is an indication for this:

There are three common solutions to this problem:
- Rewrite the Snakemake workflow, i.e. the software you are using, to use shorter paths. Or ask the developers for help. (Slow to implement solution, not necessarily stable and sustainable but permanent and it helps all users).
- Move the software and your workflow to a directory with a shorter path. I.e. in your case from
U:\Lab\Bereket_public\custom_merfish_rig\MERlin_epigen_UCSDtoU:\Merlin_epigen_UCSD. This can but is not guaranteed to help. (Easy and quick to implement, not guaranteed to work) - You can also allow for longer paths in Windows, see this article for details. I've found this solution in the past to work reliably. (Requires some technical knowledge and elevated user privileges, does not transfer to other users or machines).
Unfortunately I'm not aware of any snakemake-based solution to handle this problem.
