Hi, During installation of the newest XP-version of the PTB, I experienced the same problems as some other people posted about. I could not find a fix here, so i decided to solve them by myself. The following is a report of what i did. ======= ERROR 1 ======= ??? Error using ==\> DownloadPsychtoolbox Cannot find the specified directory, "C: PROBLEM: It tries do execute rmdir(p,'s'), with p = '\Applications\Psychtoolbox' What it then tries to remove is (at least on my machine) "C:\MATLAB7 \work\\Applications\Psychtoolbox", which is not right. QUICK AND DIRTY SOLUTION: Add the following to "DownloadPsychtoolbox.m", line 244 (so, right before the line that says [succes,m,m]=etc): S = pwd; p = [S(1) ':' p]; ======= ERROR 2 ======= ??? Error using ==\> DownloadPsychtoolbox Can not find specified file or directory. PROBLEM: Same problem basically. The intention is to set the file attributes of C:\Applications\Psychtoolbox and subdirs, but it actually tries to set those of "\\\Applications\Psychtoolbox" (where \ is "C:\Matlab7\work" in my case). QUICK AND DIRTY SOLUTION: Same as well. In DownloadPsychtoolbox.m, add the line S = pwd; p = [S(1) ':' p]; right before the line saying [S,m,mm]=fileattrib(p,'+w','a','s'); (this is line 317 if the previous modification has been applied) ======= ERROR 3 ======= After solving ERROR 2, i get a very strange error. It says: Warning: See help sprintf for valid escape sequences. > \> In DownloadPsychtoolbox at 323 ??? Error using ==\> DownloadPsychtoolbox and then something like "Hidden file will not be re-set", with all letters duplicated about 20 times (HHHHHHHHHHHHHHHHiiiiiiiiiiiiiiii etc). PROBLEM: Didn't bother to find out what the exact problem was. Just solved it. QUICK AND DIRTY SOLUTION: Replace the line saying: [s,m,mm]=fileattrib(p,'+w','a','s'); with: [s,m,mm]=fileattrib(p,'+w','ahs'); (this is line 318 in my version, the line following the one you added to solve ERROR 2) ======= ERROR 4 ======= COPYFILE error. Could not update the UpdatePsychtoolbox.m file to latest version. ??? Error using ==\> DownloadPsychtoolbox PROBLEM: Again a path problem; see above QUICK AND DIRTY SOLUTION: In downloadpsychtoolbox.m, add: S = pwd; pServer = [S(1) ':' pServer]; right before the line saying [success,m,mm]=copyfile(pLoose,pServer,'f'); (Line 346 in my version) Yahoo! Now it works: --- Updated the file UpdatePsychtoolbox.m to latest version. You can now use your newly installed Psychtoolbox. Enjoy! --- Hope this helped. Kind regards, Ronald vd Berg ---

Hello, i've modified the DownloadPsychtoolbox.m file to make it hopefully a bit more robust on Windows and MacOS-X. I can' test easily how well it works on Windows, so i've uploaded the file into the "Files" section of the Psychtoolbox forum. Could some Windows users test the new downloader and tell me if it works well, so we can upload it to the official Psychtoolbox website? Thanks, -mario > --- In [psychtoolbox@yahoogroups.com](mailto:psychtoolbox@yahoogroups.com), "rnldvndnbrg" \ wrote: > \> > \> Hi, > \> > \> During installation of the newest XP-version of the PTB, I > \> experienced the same problems as some other people posted about.

Dear Harshil, Someone can probably help, but you'll need to report the problem you're having more precisely. keith > On Jun 5, 2006, at 3:10 PM, harshil shah wrote: > > \> > \> Hi friends, > \> > \> Can someone plzz help me with a matlab code for Biological motion > \> simulation. ---
