30-Aug-96 2:40pm Dear John, I've been looking at the tools etc, but I wanted to know if there is particular tool, kind of a turn key tool, which would allow me to check directly if a file were compatible with the mmCIF dictionary and ddl. Specifically something like 'CIFCHECK file_in' and the output would be a series of diagnostics to let me know if the file was OK or not. It would be particularly nice if this could run locally given the mmCIF dictionary and ddl. Looking forward to hearing form you. Best regards, Joel
