I am struggling mrmath and the struggle is so basic I am worried I am doing something very stupid. But I simply can not see what.
So I try to use mrmath and the usage is simple enough, but I can’t seem to be able to do the simple most things with it, but always get the error
mrmath: [ERROR] unexpected value supplied for argument “operation” (valid choices are: mean, median, sum, product, rms, norm, var, std, min, max, absmax, magmax)
I use the command:
mrmath b0s.mif mean mean_b0_AP.mif –axis 3
