:orphan: .. _ahelp_3dTSgen: ******* 3dTSgen ******* .. contents:: :local: | .. code-block:: none This program generates an AFNI 3d+time data set. The time series for each voxel is generated according to a user specified signal + noise model. Usage: 3dTSgen -input fname fname = filename of prototype 3d + time data file [-inTR] set the TR of the created timeseries to be the TR of the prototype dataset [The default is to compute with TR = 1.] [The model functions are called for a ] [time grid of 0, TR, 2*TR, 3*TR, .... ] -signal slabel slabel = name of (non-linear) signal model -noise nlabel nlabel = name of (linear) noise model -sconstr k c d constraints for kth signal parameter: c <= gs[k] <= d -nconstr k c d constraints for kth noise parameter: c+b[k] <= gn[k] <= d+b[k] -sigma s s = std. dev. of additive Gaussian noise [-voxel num] screen output for voxel #num -output fname fname = filename of output 3d + time data file The following commands generate individual AFNI 1 sub-brick datasets: [-scoef k fname] write kth signal parameter gs[k]; output 'fim' is written to prefix filename fname [-ncoef k fname] write kth noise parameter gn[k]; output 'fim' is written to prefix filename fname The following commands generate one AFNI 'bucket' type dataset: [-bucket n prefixname] create one AFNI 'bucket' dataset containing n sub-bricks; n=0 creates default output; output 'bucket' is written to prefixname The mth sub-brick will contain: [-brick m scoef k label] kth signal parameter regression coefficient [-brick m ncoef k label] kth noise parameter regression coefficient ++ Compile date = Oct 13 2022 {AFNI_22.3.03:linux_ubuntu_16_64}
