How to handle a .tpvec file

I was wondering if exist an application on Materials Studio 5.0 software, or a program or code (on C, Fortran or Matlab) to handle properly .tpvec files. Because Im interested on

the coefficients of the atomic orbitals to understand how they contributes to PDOS. The information that appears on Mat. Sudio Help, is not enough to me.

Any suggestions should be appreciated

Thanks
