Hi Kerstin,
By design, the default files are put in the directory where
x3dna-dssr is run. In your case, it seems you are running DSSR from your home directory, and that's why all the dssr-*.* files are directed there. To get the auxiliary files together with the main DSSR output file, switch to the directory where you want to put all the files. Suppose you have '1msy.pdb' in
~/tmp/dssr-run/1msy.pdb, then you can do:
cd ~/tmp/dssr-run/; x3dna-dssr -i=1msy.pdb -o=1msy.out
You may want to put directory switching in a script for batch processing of many PDBx/mmCIF or PDB files.
HTH.
