Modify the source & recompile. We did it for a huge number of
restraints/molecules etc... RESP needs to be modified & recomplied
See $AMBERHOME/src/resp/resp.f
parameter (maxq = 2000)
parameter (maxlgr = 200)
parameter (maxmol = 100)

No it works for more than 8: you have to use a new line in this case...
Use RED-I with 10 orientations and you will get it. I can also send you the
un-official RED-II web site for multi-conformation & multiorientation RESP fit
if you wish...

Please use RED-I or better RED-II and all is done automatically.
