To SPMexperts,
I was wondering if anyone has successfully applied or modified SPM for use
in analyzing fNIRS/optical imaging data?
Essentially, our team has a device that measures from 16 'voxels' in a 2 X 8
matrix. We typically measure over the frontal lobe. we currently employ both
block and event-related experimental designs.
If anyone could help with a modification of SPM to be able to load the data
and implement the statistical procedures in SPM for our analyses, we would
be greatly appreciative.
I have attached a sample .nir data file, which can be opened using a text
editor or MS Excel. The text file is organized as such:
Column #1 = Time of acquisition.
The remaining voxels are organized as such:
Column 2: voxel #1, wavelength-730,
Column 3: voxel #1, wavelength-805
Column 4: voxel #1, wavelength-850
Column 5: voxel #2, wavelength-730
Column 6: voxel #2, wavelength-805
Column 7: voxel #2, wavelength-850
Column 8: voxel #3, wavelength-730
etc...
...
Column 49: voxel #16, wavelength-850
This represents our 16 acquisition voxels for the three wavelengths within
the near infrared spectrum "optical window" for detection of oxygenated and
deoxygenated hemoglobin (805 is more of a control wavelength, actually).
