Hello,

We collected fMRI data from a Bruker Biospin magnet (3 T). The original raw data from the scanning sessions were got in a file format called Paravision - a proprietary format from Bruker. This apparently is used for medical images. It was suggested on their website to convert this data to the Analyze format for scientific research purposes. So, there is a program called Bru2Anz which does this in Windows. I converted this data in Windows and then transferred it onto a Linux machine running AfNI. The Bru2Anz program returned a series of .hdr and .img files for each run of my experiment. I then performed - to3d subj_run.hdr, to3d -time, motion correction, regression analysis and finally adwarp on this data (in that order). On running AfNI, I keep getting this WARNING: NO ANALYZE ORIGIN FOUND IN FILE and this is repeatedly displayed for all the time series runs.

Also, I do not see any significant activations in my subjects data. At the same time, the our collaborators processed the same data using SPM and they could observe good activations. Is there something which I am missing in performing my analysis ? Please do let me know.

Thanks.
Abhishek.
