Hello!
I’m not able to generate a score.sc file because something is not allowing me to dock my ligands to my protein. I get the error
Cannot normalize xyzVector of length() zero
Error: [ ERROR ]
Error: [ ERROR ] Treating failure as bad input; canceling similar jobs
Here’s an example of my params file. I’ve attached a copy of my ligand/receptor .pdb and my dock.xml as well:

I looked back at my .mol2 files for compounds that dock vs those that don’t…. It’s pretty obvious the problem is with the mol files. I used open babel to create the mol files….. Is there some reason why the coordinates read 0 0 0? Here’s an example of the mol file for a compound that does not dock:

I think the error might be related to the coordinates in the paramaters file….. I compared it to compounds I have used before that have successfully docked. These compounds all have coordinates 0 0 0 whereas compounds that have docked successfully actually have non zero values. I’m thinking the problem might be with parameterization….. Here’s the script I use to do the docking.
#!/bin/bash
echo -n “Enter the name of the receptor pdb file:”
read receptor
for files in ligand*.mol2
do
/users/PHS0297/ohu0515/rosetta/main/source/scripts/python/public/molfile_to_params.py -n “Out${files%.mol2}” -p “Out${files%.mol2}” $files
cat $receptor “Out${files%.mol2}_0001.pdb” > “Out${files%.mol2}_wReceptor.pdb”
~/rosetta/main/source/bin/rosetta_scripts.static.linuxgccrelease -in:path:database /users/PHS0297/ohu0515/rosetta/main/database/ -in:file:s “Out${files%.mol2}_wReceptor.pdb” -in:file:extra_res_fa “Out${files%.mol2}.params” -out:nstruct 3 -parser:protocol /users/PHS0297/ohu0515/dock.xml
mv “Out${files%.mol2}_wReceptor_0001.pdb” “${files%.mol2}_docked_0001.pdb”
mv “Out${files%.mol2}_wReceptor_0002.pdb” “${files%.mol2}_docked_0002.pdb”
mv “Out${files%.mol2}_wReceptor_0003.pdb” “${files%.mol2}_docked_0003.pdb”
sort -n -k50 score.sc | head -n 100000 | awk ‘{print $2 “t” $50 “t” $NF}’ > reportcardirf3.dat
done

I think I resolved my own problem here but wanted to post the solution in case anyone is having a similar problem. The ligands I created using Data Warrior were smiles. When I converted these smiles to .mol2 files using open babel I did not use the –gen3d option. This is essential because rosetta needs the 3d coordinates. Here’s why. http://hjkgrp.mit.edu/content/geometries-strings-smiles-and-openbabel

Your journey of self-discovered-solutions has led you to the correct place. Rosetta is angry that the coordinates are garbage – specifically that the torsion angle between 4 atoms that are all at the origin is undefined. I think your tracing the problem upstream to a bad SMILES->conformation conversion is correct.
