Dear MIRtoolbox Users, It was quite a bad news to hear last week that there was an important error in the code of mirspread, leading to errors in the results of mirspread, but also of mirskewness and mirkurtosis. Thanks a lot to the participants of the MIRtoolbox discussion list for their great help in detecting such errors. In that same list, we sent the corrected code for mirspread. You can now find on our website a new version 1.3.1 of MIRtoolbox, which is exactly the same as 1.3 except for that bug fix concerning mirspread. Thanks for your understanding, All the best, Olivier Lartillot
