Dear list, I have downloaded the latest update of spm_graph (01/11/05) from ftp://ftp.fil.ion.ucl.ac.uk/spm/spm2_updates/. I have found that the bug relating to parametric and Volterra plots (see http://www.jiscmail.ac.uk/cgi-bin/wa.exe?A2=ind03&L=spm&P=R509481&I=3) is still contained in this file version. I think it should be corrected. All the best, Marco -- Marco Tettamanti, Ph.D. Department of Neuroscience Scientific Institute San Raffaele c/o L.I.T.A. - room 25/5 Via Fratelli Cervi 93 I-20090 Segrate (MI) Italy Tel. +39-02-21717552 Fax +39-02-21717558 email: [log in to unmask]
