MATLAB script throwing error on TrainFiles line 36 of CreateDatabase.m #15

Closed ctargon closed 8 years ago

ctargon commented 8 years ago

not sure when someone last modified this file, but its throwing an error of the following:

run_ica(false) Error using vertcat Number of fields in structure arrays being concatenated do not match. Concatenation of structure arrays requires that these arrays have the same set of fields.

Error in CreateDatabase (line 36) TrainFiles = [TrainFiles; entries];

Anyone recently change this file?

Do you have the wrong folder name for where the images are? Did you run it with the script?

Did we ever resolve this?

So the issue is primarily a MacOS issue. MacOS doesn't have the "shuf" command that is standard in linux. You can download a package that installs it as "gshuf" for MacOS so we could change a script to use that command when running on MacOS possibly. Additionally, Matlab is reading the orl_faces directory and including .DS_Store (a MacOS hidden file) and "." and "..", which was crashing the code. I think this is primarily a MacOS issue that we can talk about at the next meeting, but for now we can close this issue.
