Hi,

try:

hey

I'm getting another error

Error in backgrndsub (line 13)

[Walter Roberson]

what are you expecting the 0, [] to signify ?

[Stephan]

following the documentation for imwrite there are no option that can be specified the way you do. i edited my answer this way.

More errors?

i do not find a Matlab function named tiffwrite for 2018b. is it your own function or from another source? maybe you are looking for write.

[Walter Roberson]

tiffwrite appears in some third party contribution including in some textbooks that supply their own libraries .
