The multi-colour package used in the COMBO-17 and MANOS surveys requires a set of environment variables which you should define in your .cshrc-file. See this example:
setenv MCC /photo/user/exe/MCC setenv MCCTAB /disk-a/mambo/midas/prg setenv WFI /photo/user/exe/WFI setenv PM /photo/user/exe setenv CADIS /photo/user/exe/CADIS setenv PHOTDATA /photo/user/tbl/PHOTDATA setenv PHOTSTDS /photo/user/tbl/PHOTSTDS/CADIS
