Struct contents reference from a non-struct array object. What is this error and how to resolve it.

Answer 1

[Fangjun Jiang]

In your code, variable "filename" is a string. It does not have the structure field ".name".

If your code looks like this, then you can use filename(1).name

filename=dir('*.tiff')

Please find the detailed documentation for function "fullfile".

https://www.mathworks.com/help/matlab/ref/fullfile.html

"fullfile" returns full file name from input argument.

In your case, you need to use "dir" to find all the interested files.
