Hi Farnaz,
In our lab we use ImageJ (http://rsb.info.nih.gov/ij/). By default it doesn't come with the 'Multi FDF
Opener' plugin (http://rsb.info.nih.gov/ij/plugins/multi-opener.html), so you will need to
download and install it. This is very simple- the instructions are on the ImageJ wesbite, both in the
main documentation and each plugin's webpage.
From what I remember the Analyze reader and writer plugins are included by default- if they are
not, you can find them here- http://rsb.info.nih.gov/ij/plugins/analyze.html.
After opening the FDF image(s) into ImageJ, before writing them as Analyze, convert them to 16-
bit (Image>Type>16-bit), then process them with another plugin called 'Convert to Signed 16'.
This allows SPM to read the Images properly.
The above can all be automated using the ImageJ macro language, although if you write a macro it
is better the use the 'FDF reader' plugin (http://php.iupui.edu/~mmiller3/ImageJ/), as in my
experience the Multi FDF opener cannot be called from a Macro.
The raw Varian FID can also be opened in MATLAB (http://www.mathworks.com/matlabcentral/
fileexchange/loadFile.do?objectId=7449&objectType=file), though I haven't used it much. If your
images involve any complicated reconstruction it probably won't work.
Hope this helps
Nad
