I have another simple question. If I have a pdb file of the sort shown below, and I have to change the residue numbers from say 301 to 401, 302 to 402 and so on, is there a simple way to do it using VMD or any text commands? I have tried cat filename.pdb | awk '{print $1 $2 $3 $4 $5 $6+100 ... }' > newfile.pdb
But this new file is not being read by VMD, must be the format error (the spacings between different columns in the line). Is there a way in which I can get a nice spacing, like how we get when we use the "writepdb" ?
I need to change the residue numbers as I was trying to merge different files with same resid numbers, but different coordinates.
Thanx
Uday
