FYI, For anyone else merging independent I/A networks, you need to check CSAs for duplicate compounds before merging. One easy way is to first do a CSA_Save on both networks (you need to do this anyway): # cd /usr/fox/csa # mkdir save # CSA_Save ./save Then get a list of the compounds to a file: # cat ./save/* | awk '{print $1}' | sort -u > compounds.tmp Do the same for the other I/A system to compounds2.tmp and copy compounds2.tmp to the same place you have compounds.tmp. Then generate a list of common compound names: # comm -12 compounds.tmp compounds2.tmp VOLWRK_VECB VOLWRK_VSTA VOLWRK is to be expected, other compounds may of course take a little more engineering.
