Hello, I was wondering if 3dDeconvolve can recognize differences in stim .1D files. For example, say if I have 3 stimuli temperatures in my model: cold,warm, and hot. Normally I would set up .1D files containing 1's and 0's for the respective stimuli rest and onset conditions for cold, warm, and hot.

However, I want to scale my stim-.1D files based on averaged-temperature subject ratings of cold (35 degrees), warm (56 degrees), and hot (77 degrees). Thus, my cold-stimulus .1D files would contain all zeroes indicating rest and 0.45's indicating when the stimulus is applied. The warm-stimulus .1D files would contain all zeroes indicating rest and 0.73's indicating when the stimulus is applied, and the hot-stimulus .1D files would would contain all zeroes indicating rest and 1's indicating when the stimulus is applied. Is this possible to do with 3dDeconvolve ? Or, is there another procedure I could use? Any help would greatly be appreciated.

Thanks
