Dear Andrea I had a similar problem and the following tip ("Windows Classic Style") from Mathworks site worked fine. Although SPM is running, segmenting imagens is too delayed with XP (http://www.jiscmail.ac.uk/cgi-bin/wa.exe?A2=ind0111&L=spm&P=R105504) With best wishes. Griselda. "Windows Classic Style" tip from http://www.mathworks.com/support/solutions/data/29388.shtml: Is MATLAB supported under Windows XP? Solution: MATLAB 6.1 (R12.1) and earlier versions are not officially supported under Windows XP. Currently, MATLAB 6.1 (R12.1) for Windows is supported under Windows 95, 98, NT, ME, and 2000. For more information on the system requirements for MATLAB, please see the following URL: http://www.mathworks.com/products/system.shtml/Windows Windows XP is expected to be officially supported in our next release of MATLAB 6.2 (R13), though this is subject to change. If you are currently using Windows XP and MATLAB 6.x (R12.x), please note that we have experienced some incompatibilities with MATLAB 6.1 (R12.1) and Windows XP. As a workaround, please use Windows XP in the "Windows Classic Style" mode, which seems to prevent most of the conflicts. The "Windows Classic Style" can be set with the following steps: 1. Choose the Control Panel from the Start Menu. 2. Choose Appearance and Themes from the Control Panel. 3. Choose the Display Control Panel Icon from the Appearance and Themes menu. 4. Select the Appearance Tab. 5. Under Windows and Buttons, change the display to Windows Classic style. -----Mensagem original----- De: SPM (Statistical Parametric Mapping) [mailto:[log in to unmask]]Em nome de Andrea Boghi Enviada em: segunda-feira, 3 de dezembro de 2001 12:31 Para: [log in to unmask] Assunto: spm and windows xp dear spmrs, is there anyone who has tryed to use spm with windows xp? i have tryed but after tiping "spm" in the matlab prompt the spm interface does not open; only a little bar is opened which is not functional... may i return to older windows version?
