The error would indicate the file doesn't exist. Have you double checked your directory is correct, and the file name doesn't have a missing character or something?

[Younis Firwana]

I double checked the file and it is already existing in m directory. what do you mean that file name doesn't have a missing character or something?

[Bob Thompson]

I simply meant that with a file name that is long and complex it is easy to mistype the name, causing the file name variable in MATLAB and the actual file name to not match.

I suspect that something like this is the most likely cause for the error because the error calls a specific file name, rather than saying that the following variables are trying to use an empty value for the file.

if you have any way to solve this problem so tell me in details, please

'cp' is not recognized as an internal or external command, operable program or batch file.

The code is trying to execute a Mac or Linux command to copy a file. Everything past that could fail because the file is not copied.

As a work around you could locate copy.exe and copy it to cp.exe

First of all, the variable fslabsolutepath is not defined in your base workspace so that's why setenv() didn't work.

Then the ASL_GUI program didn't work because it couldn't find "C:\Users\Younis\Documents\research\naser\t1\aux20181005_091325T1W3DSAGSENSEs1201a1012.nii". What does this show:

>> filename = 'C:\Users\Younis\Documents\research\naser\t1\aux20181005_091325T1W3DSAGSENSEs1201a1012.nii';
>> fileExists = exist(filename, 'file')  % Don't use a semicolon.
