I was trying to find the mean of whole 3D volumes in noise series. There was no transmit power such that we were collecting pure noise from the system ( phase array, receivers, preamps, etc). Is there a tool in AFNI for this purpose? 3dMean or 3dTstat can’t do this.
Is “3dBrickStat -mean” what you want?
It seems 3dmaskave is an even better tool for this.
The programs have different uses.
3dBrickStat would return the overall mean from an
entire 4-D dataset, while 3dmaskave or 3dROIstats
would return one mean per volume, i.e. possibly a
time series of means.
