Hi folks, Today, I tried using PALM to load CIFTI files directly in order to estimate some simple 1 and 2 sample t tests on some HCP-processed data I've got from one of my projects. But I quickly ran into a problem. Anderson Winkler and I just talked about it via email. He pointed out that I was trying to load 45 dense-data activation map images into PALM in a way that the program interpreted as needing to have only 45 datapoints along the first dimension. In other words, PALM doesn't like the CIFTI output from HCP's fMRI modelling script when it's loaded directly using the -i input specification.
Anderson suggested things might work more easily if I merged these CIFTI files into a 4D file. But he also suggested I pay close attention to how the data was oriented so that PALM interprets things right. I know I could instead follow previous posts about splitting the data up into NIFTI volume vs. surface data, running stats, and ultimately recombining, but I was hoping that PALM really could do everything in one step if the CIFTI stats file data was prepped right, as that'd make it a bit easier to try out all the cool statistical options Anderson built into PALM across the various HCP datasets I've got at hand. Can anyone whose dealt with this or a similar problem before tell me exactly how to invoke the wb_command -cifti-merge command to collapse into 4D and to orient these CIFTI data properly for PALM group-level analyses?
