.gif files

Hi Jaewon,

When I try to call a .gif file using ImageGraphic, I get the error "PIC: Number of elements must not change. Use [] as one of the size inputs to automatically calculate the appropriate size for that dimension." Any ideas what might be the issue?

When I put [] as one or both of the size inputs, I get the error "Can't parse out".

I also get the first error if I don't specify size at all.

ImageGraphic does not take any size argument nor produce an error message prefixing "PIC". Please double-check which function/script made the error.

Sorry, I should have been more specific. The error happens when I create a scene that includes ImageGraphic and call the taskobject from the userloop. It works fine with static images but not gif images. Here is the section of code causing the issue:

img1 = ImageGraphic(eye_);
fix1 = SingleTarget(img1);
fix1.Target = fix_cue_img;
fix1.Threshold = fix_cue_threshold;
fth1 = FreeThenHold(fix1);
fth1.MaxTime = fix_cue_max_response_time;
fth1.HoldTime = fix_cue_required_hold_time;
scene1 = create_scene(fth1, fix_cue_img);

fix_cue_img is the taskobject from the userloop file and can be a static image or gif (chosen by user via editable)

Here is all the error info:

Error using mlconditions/parse_object (line 123)

Animated GIFs are not supported. Make it as a movie.

ImageGraphic is not doing anything in your script. You may as well remove it.

Ok. I assumed animated GIFs were supported based on this table that says GIF is an acceptable format for static images: [monkeylogic.nimh.nih.gov]

I understand now that it is referring to static GIFs only.

I will make it a movie instead. Thank you.

Update your NIMH ML and you will be able to use GIF as a movie source. Use MOV, instead of PIC.

Thanks Jaewon, works great.
