Follow-up Comment #3, bug #8997 (project relax): Hi, The problem seems to be related to the parsing of the 'mfout' file, especially for what concerns the chi2 for the residues (end of the file, section 'data_sse'). This part of the 'mfout' changes drastically when simulations are done. If the section 'data_sse' is transformed to look like one when no simulation is performed, the error message is the same, but for the next model (m2). Maybe the parsing of the mfout needs to be different depending if simulations are performed or not.
