PDB write & Molviewer give dimensional error

Hi everyone!

I try to alter and superimpose multiple pdb files. I read the file with pdbread and can also transform it with e.g. pbd transform. But when I try to use either molviewer to look at the alterations (or the original read file) or try to save it with pdbwrite I get the error 'Dimensions of arrays being concatenated are not consistent.'

Because this also happens with unmodified pdb files, is there anything I am doing wrong with the reading? Or do I have to alter the MATLAB-Generated file before saving/viewing is possible?

Your help is really appreciated.

My very simple test code:

%read file
a=pdbread('C:\Users\zechmeisterin\Desktop\4d5q.pdb'); %PDB file downloaded directly from PDB website
pdbwrite('C:\Users\zechmeisterin\Desktop\modified4d5q.pdb',a); %save original
molviewer(a)
transf.T = eye(3);  transf.b = 1;  transf.c = [11.8 -2.8 -32.3]; % test transformation from mathworks

pdbtx = pdbtransform(a, transf, 'segment', 'all');
pdbwrite('C:\Users\zechmeisterin\Desktop\modified4d5q.pdb',pdbtx); %save modified
