Return to Source Localization - SAM
Description
The program NIFTIPeak is designed to find the peaks in all NIFTI volumetric image files in the SAM subdirectory of a named dataset. It is similar in function to the AFNI program 3dExtrema, although NIFTIPeak was created specifically for finding peaks in images produced by SAMepi.
Usage
NIFTIPeak -r <dataset>
Other options:
| -t <threshold> | Threshold for peak detection, usually a Z value. Defaults to the RMS intensity |
| -s <size> | radius of the maximum search - individual maxima must be further apart than this distance to be considered separate maxima. Default value is twice the voxel dimension. |
| -n <max> | Maximum number of maxima reported. Defaults to 10. |
| -p | List the power in the output file |
Output Files
This outputs a single text file, giving the coordinates of each maximum, as well as the power if requested with the -p option.
