Optic can not load mat data

[FengJin2023]

After I load a .mat data into optic. Below error message has popped up.
Could you take a look what is the problem is?
*** The oi fov is not set yet. Using the scene fov.
*** The oi fov is not set yet. Using the scene fov.
*** The oi fov is not set yet. Using the scene fov.
Warning: Variable 'opticalimage' not found.

In vcLoadObject (line 56)
In vcImportObject (line 44)
In oiWindow_App/menuFileLoadOI_Callback (line 874)

In this case, I am not sure what action you are taking. I will check if you tell me what file you are loading. The warning (fov is not set yet) can happen if the oi is not set. The oi field of view (fov) is inherited from the scene via oiCompute(oi,scene); Anyway, this one looks like some edge case of usage. I will try to handle it once I know what you did to get here.

Thank you for your reply.
I was trying to do below.

1. Make scene image from 'scene'.
2. Save it as .mat file
3. Open it in 'optic'.

Attached it the file I used.

I am sorry, but I don’t really follow this. Why would you try to open a scene struct, saved in a .mat file, as an optic? The computational path is to define the optics properties in an oi, and then to use oiCompute to render an optical image from the scene, such as Scene = sceneCreate; Oi = oiCreate; Oi = oiCompute(oi,scene).

I misunderstood the working flow of the tool.
I successfully get images in OI and Sensor.
However, I got another problem on processor. I will open a new questions.
Besides, I have some general questions regarding settings. Shall I wrote it by email or github?

Good to have the issues on GitHub. Thanks. Brian Wandell Stein Family Chair Stanford University Http://www.stanford.edu/~wandell
