Matched descriptors, but aligning and scoring does not occur

[seojinleee]

I tried running MaSIF-seed on 7XYQ_A (from the paper), and while it matched with descriptors, the second stage of MaSIF seed search failed to proceed.

# MaSIF-seed
./run_target_protocol.sh 7XYQ_A

cd targets/7XYQ_A/
./run.sh 7XYQ_A

# output: 
Starting to match target descriptor to descriptors from 2 proteins; this may take a while.
Iterated over 744 fragments from 1 proteins; matched 12 based on descriptor similarity.
 
Second stage of MaSIF seed search: each matched descriptor is aligned and scored; this may take a while..
# nothing appears
# no output files at /masif_seed/masif_seed_search/data/masif_targets/targets/7XYQ/out_peptides/7XYQ/site_0

For the tutorial protein 4QVF, I get the following output, so the code itself runs fine:

# output
Starting to match target descriptor to descriptors from 3 proteins; this may take a while.
Iterated over 1468 fragments from 2 proteins; matched 32 based on descriptor similarity.
 
Second stage of MaSIF seed search: each matched descriptor is aligned and scored; this may take a while..
Selected fragment: 0 fragment_id: 4QVF000_B score: 0.9946 desc_dist_score: 55.1651 clashes(CA): 0 clashes(total):0

Surface alignment is deactivated - aligning only pdbs. 
Selected fragment: 2 fragment_id: 4QVF000_B score: 0.9934 desc_dist_score: 36.8498 clashes(CA): 0 clashes(total):0

Surface alignment is deactivated - aligning only pdbs. 

Has anyone faced this kind of issue?

Also, other than the tutorial protein 4QVF, none of the proteins that I tried doesn't work. It either matches with no descriptor or fails to go on to the second stage of seed search.
