Dear Maria, This behaviour was changed three years ago for "contrast estimates" plots so that they can be displayed even if the raw data are no longer accessible. ------------------------------------------------------------------------ r6963 | guillaume | 2016-12-07 16:34:44 +0000 (Wed, 07 Dec 2016) | 2 lines Changed paths: M /trunk/spm_graph.m Enhancement: only read raw data when relevant for plotting. Thanks to Christian B. ------------------------------------------------------------------------ To access the 'y' and 'Y' variables, use a "fitted responses" plot: these variables are directly available in the MATLAB workspace. You can also access raw data and contrast estimates through the contextual menu that appears when clicking in the MIP image. Best regards, Guillaume.
