Hello,
There is some more detail in the feat manual ( http://www.fmrib.ox.ac.uk/fsl/feat5/detail.html#tsplot ) but basically
tsplot_zstat<number> is the full model fit vs the data, for the most significant voxel
tsplotc_zstat<number> is the full model fit vs the data, averaged over all significant voxels
tsplot_zstatp<number> is the partial model ( model due to contrast ) vs the reduced data ( data - model + partial model ) for the most significant voxel
tsplotc_zstatp<number> is the partial model ( model due to contrast ) vs the reduced data ( data - model + partial model ) averaged over all significant voxels
The Y-axis is in units of "parameter estimate"
Hope this helps,
Matthew
> Good afternoon. Could anyone tell me what is being plotted in the tsplot_zstat1, tsplot_zstatp and tsplotc_zstat1? And what the Y scale is? I understand it is a value associated with each of the lower level inputs but what are the units? Is it a measure of variability between runs using the same experimental paradigm? Is a straight line what you are looking for in the plot? I use rhesus macaques as subjects so it is mostly just a repeated measures analysis looking at the 'average' activation for a single subject across runs, with the occasional contrasts using the copes associated with different experimental variables. Any clarification would be most appreciated.
