Error showing that basis set does not exixt.

I was trying to use 6-311Gpp basis set for caluculation. The the part of input file  is as shown

H20  12 0.96878    5  110.922      4   0.107
End of z-matrix

Even though the basis set name is a s same as the basis_library in Openmolcas it shows the error basis set does not exist.
pasted the error below

ERROR: The requested basis set label: C.6-311GPP.....                ###
 ###    was not found in basis library: /usr/share/openmolcas/basis_library/6-311GPP

Kindly suggest a reason and solution.

Re: Error showing that basis set does not exixt.

The name of the basis set is 6-311G**, not 6-311GPP. The latter is the filename (which is declared in trans.tbl, or something like that).
