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

tobBla · February 2015

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'
exception type: TypeError

Traceback (also in debug window):

  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!
Sebastiaan

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
