It is the folder name and the file name that is more important. And rpyc.zip... how does that come into play?

Dan Patterson‌, I corrected the line by replace line no 4 suggested by you. Now i am getting following error massage. Error massage displaying output raster name can't be more than 13 character. So whats is the possible way to short the output raster name

so you did see my example and you definitely want the first 12 characters of the string (line 4 in my example) and not the last 12 (ie line 4 in my example). You need to print the string prior to extracting it so we know what is it is

ShouvikJha

Dan , Neil, i extremely sorry for the late reply, here holiday was going on . Problem still persist. by this command i am trying to extract selected time spam images.

Never dealt with this sort of data before, but that error is obviously your indexing of the value in Nowfile.

So, as Dan says, perhaps have a look at that variable before this step.

DanPatterson_Retired

you had better throw a print statement in there to ensure that the negative slice doe indeed return the proper formatted year prior to testing. you might want to split on "/" and return the last slice instead to get the year itself, rather than relying on a position count.

So, what happens at the moment?

What errors are you getting or are you asking to validate this code prior to actually trying it?

I can see one problem with this :

Shouldn't you add the "*.tif" to outname in the line above. Here the "*.tif" is the 3rd parameter. Which I am sure will not work.
