Hello Dr.Huber, Ms. Ligia's suggestion seemed to have solved the problem. My Plateconf.txt had an extra column on line 5 and removing solves the issue. However I am attaching and sending you the requested files. The mailing list seems to filter out certain attachments. So if you do not get all the files, please let me know. Plateconf.txt.bak is the original plate configuration file. Thank you, Shripad Sinari Wolfgang Huber wrote: > Dear Shripad, > > thanks for the report! This is an odd error.
