The problem with this data format seems to be the 'ddd' at the beginning of the data format.
DIAdem expexts the 'dd' to be a day of a month, not a day in a year. I can offer you a solution though:
Please upload or send me two of your data files and we will create a little script in DIAdem that will import your data format and make it available in DIAdem and DIAdem CLIP.
You can upload them here in the forum or send them to me at:
otmar.foehner@ni.com
Please compress the files (with ZIP or similar technology) if they are large.
