I'm doing a program in guide to view sequentially the cuts (sagittal, coronal, axial) over time. Now i want to be able to vary the speed with which time passes, but i can't found a way to do this. I want to creat a popup menu, or a checkbox for changing the speed of a imshow like, 2x, 0.5x 0.75x, 1.75x, 1,5x

@João Pedro - you may need to provide more details. How are you currently showing the images using imshow? Are you iterating over a list of images (in a for loop) and then showing each image sequentially with a fixed pause at the end of each iteration? Or are you doing something else?

display_images.mlapp

Hi Predro,

You can try using App Designer instead of guide. Adding to the above comment, you can display series of images using pause and updating the source of uiimage object periodically. The speed can be configured using a slider component. Please refer to the attached mlapp file for the implementation of the workaround.
