when i processed this, the step 3 block the process ‘not enough gacos data’

i never met this error. maybe your gacos data is not complete?

Have you managed to solve this issue? I saw some posts saying it might be related to the MATLAB version. I’m using MATLAB 2025a and encountered the same problem. Some people suggested downgrading to 2020b. You might find this blog post helpful as well:

I found that the issue was not caused by the MATLAB version, but rather by a mismatch in file naming during my ISCE processing workflow. Specifically, the incidence angle file generated from StaMPS was named inc2.mat, whereas the APS module expects a file named la2.mat containing a variable called la.

The error was resolved by adding the following lines of code:

matlab

复制编辑

S = load('inc2.mat');
% Rename to 'la' to comply with APS requirements
la = S.inc;
% Save as 'la2.mat' with variable name 'la'
save('la2.mat', 'la');
% Set APS parameter to the new file path
setparm_aps('look_angle', fullfile(pwd, 'la2.mat'));

This ensures that the APS script can properly load the incidence angle without encountering a missing field error.
