PDBs object sidechain selection

[Former user]

Hi, Is there a way to create an object with only the sidechains from the PDBs object. I have in mind a PCA analysis using the sidechains only.

Will appreciate any help.

Regards, BM

Please check out read.all() function, which read coordinates of all heavy atoms in an aligned manner. Then, pick up side-chain atoms by checking atom names and do the PCA.
