There is no p-value map. Rather, you create contrasts (after you estimate the model) that create either: (1) spmT_ and con_ images or (2) spmF_ and ess_ images. The con_ images provide you with a measure of the magnitude of the contrast. The spmT_ and spmF_ images provide you with either the T-statsistics and F-stastistics at each voxel. From those values, you can determine the p-value.
Hello,Just a simple question as the subject.The second level analysis produces a lot of files, I wonder which one contains or is the p-value map.RPV? mask? ResMS?And what exactly does the p-value map show? Is it simply a mask which sets '1s' for the pixels larger than the value,'0s' for others?I am totally a freshman for the analysis procedure, maybe you can explain in a easier way:)Thank you so much.Best Regards,Yuan
