Interpreting HRF export-Extracting analyzed data values
Nicollette, please plot the first column of the excel file (time) and any other column (e.g. the second one), you will see the HRF is baseline corrected i.e. you will see that the values before 0 are around 0 since the whole HRF time course is baseline subtracted within the GLM function (by the mean of the time range before stim that you picked e.g. -2 to 0, if the trange you picked is -2 to 10). For stats you can take the mean of the HRF around the peak activation, this will change depending on your stimulus type and duration.
Thanks for the response Meryem, I appreciate the help. I think that makes sense-I just have to get more comfortable working with the data. Thanks again!
