How to identify the exact file which throws out the warning during batch conversion of files using obabel in bash?

Question

I am using obabel tool to batch convert a set of SDF files to PDB file.

 obabel *.sdf -opdb --gen3d -m

I have ~50000 files and i am getting totally of 12 warnings in total (warning mentioned below).

How do I identify the exact 12 files which have created this warning?

Edit:

As suggested, I tried to use --errorlevel 3. But sadly, that also did not help to identify the exact ligand throwing out the error. I am pasting the output got with the code. It is similar to the earlier one.

obabel *.sdf -opdb --gen3d --errorlevel 3 -m

obabel *.sdf -opdb --gen3d --errorlevel 3 -m

Answer 1

I don‘t know the software but if there are no interdependencies between the files you can run

for i in *.sdf; do
    echo "$i"
    obabel "$i" -opdb --gen3d
done
