Dear Sir or Madam,
I have recently installed and compiled Rosetta2019.14 (without binaries) on OS Linux OpenSUSE Leap42.3. And I started to study Rosetta in according to file "folding_tutorial.pdf" from the Meiler lab. But after every handling with files and directories on the Rosetta through an Unix terminal that directory becomes unavailable for every operation with it. For example, after running such operation as: "python2.7 /home/ihor/Документи/Rosetta/rosetta_src_2019.14.60699_bundle/tools/protein_tools/scripts/pdb_renumber.py \2LZM_A.pdb 2LZMA.pdb" I tried to save edited PDB-file to a directory, where I work. And I got such error: "The document can not be saved due to a write error to /home/ihor/Documents/Rosetta/rosetta_workshop/protein_folding/2LZM_A.pdb. Make sure you have the right to write to this file and have enough free space." Also, after running such command, as "python2.7 /home/ihor/Документи/Rosetta/rosetta_src_2019.14.60699_bundle/tools/protein_tools/scripts/pdb_renumber.py \2LZM_A.pdb 2LZMA.pdb" I got such error "ERROR: This script requires that Biopython (http://biopython.org) is installed.", despite that biopython had been already installed. Could you tell me more detail, how to solve such problem with the Unix terminal and such error, please? Both commands and their errors are provided on the attached screenshot. I will be sincerely grateful for your response and help, and I am looking forward for it.
