you could just keep two srs trees. The only things that can be

the gcg indices ARE real srs indices!

lookup provides almost the same functionality as getz.

lookup comes with a full set of SRS programs for building indices ...the
main difference is the restriction to sequence databanks in GCG formats
so that that SRS will always be happy with lookup's indices but not
the other way round

correct

no those would have to be removed from the group

as said in the previous posting you can in you SRS installation specify
the index directory from lookup for those databanks that are supported.
