Don't use "image" as the name of your image variable - it's an important built-in function. What is the name of your file you are trying to write? If you comment out the imwrite() line, does the script run fine?

did not use 'image' this time ... used im instead, still no luck. if i comment out imwrite ..it goes through all of my images in different folders but make only the first folder where i need to save the transformed images. rest of the image directory it doesn't make . Like it prepare the folders trasnform2Dimages ->transformdata-60.. while iterating through the first folder where it's picking up the images but then it doesn't create the next folder or the folders after that . It should create folders like trasnform2Dimages ->transformdata-61 , trasnform2Dimages ->transformdata-62. Please find the updated code attached.

Paste the contents of everything that appears in the command window.

This is what i am getting if i comment down imwrite(). It keeps eso i executing for a large image database so i pasted some part of it

You can get rid of a lot of the warnings by not calling mkdir if the folder exists:

Replace

mkdir(dataFolderName);

by

if ~exists(dataFolderName, 'dir')
      mkdir(dataFolderName);
end

then you'll have to put the imwrite back in so I can see what the error for that is. Perhaps you can't write to the folder, like it's on a readonly drive or need admin permission or something.
