Greetings

Please disregard the first message I found out that there were extra ( ^M
)added to each line in the header file of the interfile header, when I
took all of them away I no longer had the message I posted earlier.
But after that , the GATE interfile reader complains thus

Error: the number of pixels that were read from the data file (1787386)
is inferior to the number computed from its header file (3574773)!

This is GATE 2.2.0 as stated on the website and the version of Xmedcon  is

conversion program := (X)MedCon

program author := Erik Nolf

program version := 0.9.8.6

program date := 2005:07:31

I look forward to hearing from anyone with simillar experiences.

Cheers

Theo
