Prank not compiling for a dataset (.ds) about p2rank HOT 11 CLOSED

Colud you attach or send the .ds on which it breaks? I will look into it...

from p2rank.

HEADER: prediction protein

dir_test/1a52.pdb
dir_test/2a52.pdb

This is how my .ds file looks like. I used only 2 files for testing. I also tried including their whole path but it doesn't work like that.

from p2rank.

In your case the header should be
HEADER: protein
because you have only one data column in the file. You can compare it with other *.ds files in test_data directory. Let me know if it helped.

I will add more halpful error message for this case. Thank you for reporting this.

from p2rank.

I tried it with HEADER: protein and it still gives me the error
"""P2Rank 2.0

ERROR: dataset contains invalid files"""

It doesn't read the files whereas when I try it with one of the .ds from test_data it works. I still don't understand why.

from p2rank.

Do all the pdb files exist? The paths should be relative to the location of *.ds file.
If so, you could try removing the heather altogether.

If it doesn't help, could you attach the zip file with your working directory including ds file and pdb files?

from p2rank.

Yes all the pdb files exist. I used the paths relative to the .ds file only. I transferred my .ds file and the directory with pdb files to test_data folder in p2rank_2.0 and it works now. I still do not understand why. I can use this but would really like to know the reason behind it.

Thanks !

It's probably a bug. Could you help me to reproduce it? I will need some more information.

What is your operating system and shell (bash/cmd/...)?
What was the exact full command that produced the error and in what directory it was executed?
What was the directory structure (location of p2rank, ds file and pdb files)?

from p2rank.

Yes I thought so too that it was a bug.
Sure.
I am using bash terminal on Kubuntu16.04. I executed the command "./prank predict test.ds -o test_output" in the p2rank_2.0 directory and my .ds file and the directory containing the pdb files were in the same folder (p2rank_2.0).
Hope it helps you to solve the bug. Let me know if you need more information.

Fixed in version 2.0.1 (https://github.com/rdk/p2rank/releases/tag/2.0.1).

@purvi24, thank you for the bug report and provided details!

from p2rank.

@rdk I'm also experiencing the issue, even in 2.0.1 and 2.1.

Running:
/opt/p2rank_2.1-dev.1/prank predict -f file.pdb works

while
/opt/p2rank_2.1-dev.1/prank predict dataset.ds doesn't

dataset.ds:
file.pdb

I was not able to reproduce the problem with version 2.0.1. Could you provide more details? What is your operating system and what was the output the run? Could you also include <p2ank_dir>/log/prank.log?

Version 2.1-dev.1 indeed has that problem but this is to be expected since it has been released before the bugfix. I will create new 2.1-dev.2 release with the bugfix, but first let's figure out what is the problem with the version 2.0.1 so I can include fix for that as well.
