[solved] Can´t open my newly created experiments (failed to open file)

tobBla

Hey everyone, it seems like i need some help again - not with actual experiment programming this time though:

I just wrote two experiments - both worked fine until i closed everything and wanted to open them again

opensesame comes up with this message when trying to open one of the files:
(no idea why the following is a wall of text -.- looks fine in edit and preview windows ... sigh)

Failed to open file
line: 47
exception message: arguments did not match any overloaded call: QTableWidget(QWidget parent=None): argument 1 has unexpected type 'unicode' QTableWidget(int, int, QWidget parent=None): argument 1 has unexpected type 'unicode'

  QTableWidget(int, int, QWidget parent=None): argument 1 has unexpected type 'unicode'

I checked the scriptfile in the tar.gz file: line47 is

set maxchar "50"

from a define text_display block... guess thats not the line47 opensesame points out...

Just created a new, empty, experiment, saved it and was able to open it... no idea why it won´t open the above two...

Edit: Some system specs: Windows 7 x64, experiments were created with os 2.9.2, tried to open with 2.9.4 aswell

Could you upload the experiment somewhere? For example FileDropper.

Hey sebastiaan,

of course! silly enough i didnt think of that myself

Hi,

Ok, you ran into a little bug (just filed it as #309). What causes the problem is that you have set the cycles variable of loop to a non-integer value:

define loop loop
    set cycles "[blockCounter]"

The GUI chokes on this, although it shouldn't. To fix this, you can extract the experiment with a tool like 7-Zip, open script.opensesame in a text editor, and edit the offending line, for example by changing it to set cycles 1. After that, you should be able to open the experiment again.

Cheers!

Oh wow - yes it works
I will use the break if condition as a workaround as long as the gui doesnt like that
Also, happy to make you find a new bug :-bd

And of course: Thanks for your quick replies! Having problems with opensesame is almost as not having problems with opensesame

Hi,
i am also having a problem re-opening my script.
I followed the tips presented in this thread and edited it but maybe I am still missing out something.
I uploaded my exp here
http://www.filedropper.com/simontaskopensesametar
(ps: it is a small exp for a tutorial, which makes everything sound even more embarassing).
Any help would be super appreciated. Thanks
Harold

Hey harold,

upon trying to open your experiment opensesame states that the file is not a gzip file.
Did you use 7-Zip to do your editing in the script?
If i recall right i edited the script directly in 7-ZIP (it still has to open the file in an editor, but i did NOT manually extract everything and then put it back together). I think it was something like right-click the script file within 7-ZIP and "edit" or something like that

Hi Harold,

I'm not sure what happened here (it might be due to filedropper), but the format of the file is a tar archive (.tar), whereas OpenSesame expect a gzipped tar archive (.tar.gz). So what you could do is rename the file to something.tar, and open it in a program like 7-zip to extract the script.

Cheers,
Sebastiaan
