My name is Uday and I would like to use fmask for Landsat 5 data. I am using your Fmask R script for automated cloud detection and I am getting some error but I do not know how to fix it. I can run code until # For each full image, subset and save it, if(length(dir (DATA_DIR_IMAGE_SUB))==0){ for(i in 1:length (DATA_PATH_RAW)){ L7CLIP(DATA_PATH_RAW_FULL[i],DATA_PATH_RAW[i],BBOX.VAL) print (i) } }

but at this point I get an error

{Error in function (classes, fdef, mtable) : unable to find an inherited method for function "extent", for signature "NULL" In addition: Warning message: In intersect(extent(x), extent(y)) : Objects do not overlap }

DATA_PATH_RAW_FULL[1] is Band 1 DATA_PATH_RAW[1] is no band BBOX.VAL get the dimensions

I think there is some issues with selecting extent , my study is in Central part of Thailand. So could somebody please tell me how to fix this problem.

I am using 120424_run_functions.r script on windows 7 professional with 8 GB RAM.

The R script is provided from colleagues from Australia and I think that version is already out-of-dated and they are updating the new version in the near feature. Try the Matlab 2.1 version or windows stand lone 2.1 version.

Thank you for reply the windows stand lone version 2.1 works fine. Is there any option we can use for batch processing ?

Actually, you can code it in cshell or Matlab M-file for batch processing.
