Hi Walter:nWhat version of Chemkin are you running? There is a known defect for mechanism reduction that use both max and endpoint for a target. Some of the error messages that occur with this defect is triggered will seem quite spurious. If RUN_000001 failed due to non convergence, the file may not get generated, and the next reduction iteration will fail.nI would recommend upgrading to the latest Chemkin release and using no more than 2-3 targets, avoiding the max and endpoint selection for the same target. Note that mechanisms that don't contain SMILES information will not run with certain reduction methods like lumping, which require Chemkin to be able to distinguish isomers.n
