Error using imwrite (line 455) Unable to open file "C:\Users\Bahar\Documents\Uni\Thesis\IMP\930620" for writing. You may not have write permission.

bkshn - I get the same error message if trying to do something similar. But look closer at the error message
Unable to open file "C:\Users\Bahar\Documents\Uni\Thesis\IMP\930620"
No extension is being supplied to the file that is being opened. Try including the extension in the file name (it isn't enough to just supply the output format of jpg) as
imwrite(a1,'C:\Users\Bahar\Documents\Uni\Thesis\IMP\930620.jpg','jpg');
The above worked (for me) when I included the extension.

I had the same issue of write permission.
Try checking if the file which you want to write already exists in the folder by below script
if exist('folder\filename.jpg', 'file')
delete('folder\filename.jpg')
end
Then try saving again by imwrite
