cartesian_ddg error: “Assertion `files.size() == 1` failed.”

[Anonymous]

I am trying to run the cartesian_ddg protocol (https://www.rosettacommons.org/docs/latest/cartesian-ddG).

I am using the following command:

cartesian_ddg.static.linuxgccrelease 

-database $ROSETTADB 

-s min_2b5i-A_0001_clean_0011.pdb 

–ddg:mut_file themutfile.txt  

-ddg:iterations 3 

-ddg::cartesian 

-ddg::dump_pdbs false 

-bbnbr 1 

-fa_max_dis 9.0 

-beta_cart

 

where $ROSETTADB points to the database directory. I am attaching the .pdb and mutfile.

I am getting the following error:

Using mutfile: themutfile.txt

This is kinda tricky — you have an en-dash before ddg:mut_file, rather than a dash. This means that you’re effectively passing a filename “<endash>ddg:mut_file” to the -s parameter, which is why you’re getting the error about number of files.

This looks to be a mistake in the original documentation (which you apparently copy-pasted). Sorry about that. I’ll fix that for the next release.

Wow, that was subtle. Thanks a lot for taking a look.
