Thanks Martin,
Yes, PAR/REC is optimal. However, immediately following the upgrade, our research key was not enabled and we were unable to export to PAR/REC. While that issue has been resolved, I have data that is only available as DICOM, but needs analysis.
We most commonly retrieve the data from our GE Centricity PACS system and then copy to the WINXP/LINUX box used for analysis.
Of note, files created by other scanners (GE and Philips) that we retrieve as DICOM from PACS do not have this problem.
If you could help me with the conversion, I would be most grateful.

Hi Michael,
as others have already suggested, export of your date to the so-called PAR-REC
(Philips research file format) file format is one way. At times it may be
even preferable, because in the PAR file, which is a simple ASCII text file,
you can get the gradient diffusion table for free.
Regarding your troubles with the Achieva DICOM files, I would guess they could
be related to the conformance of Achieva architecture to the very recent
DICOM standards. I think it is by default that Achieva exports DICOM images
in the "MULTIFRAME format". This means that you would not find 2040 files in
your 32 (+ b0 + ADC-weighted) directions and 60 slices DTI study, but instead
they would be stored in ONE single file.
You don't write how you get the images on a computer with MRIcro, so it is a
bit hard to speculate exactly, what could be the problem. If you prefer to
work with DICOMs, I would be happy to assist you to locate the problem.

Hello Philips users:
Since upgrading an Intera 3T scanner to Freewave/Achieva, I have been
unable to convert my DTI data from DICOM to any FSL-friendly format. I was
previously doing this with MRIcro and have since tried every converter I
can get my hands on, with no success.
Any suggestion would be much appreciated,
Michael
