# TIMESAT input image requirement?

I tried to work on TIMESAT but always facing a problem. Here is the method I have used. Seems correct, but I get a warning at the end.

I have created a NDVI file from ENVI 4.8 >> Transform >> NDVI >> saved Output data type as Floating Point. Next I use Basic Tools >> Stretch Data >> Stretch Type Linear >> Stretch range by value -0.036 to 0.833 which is my NDVI range to Output DATA Range to 0 to 255. and saved the DATA Type as Integer as Timesat requires 8 bit integer(0-255).

I did the same procedure for my 5 NDVI files, except I used a different Stretch range by value X to Y, based on their own range.

Now I try to open them in TIMESAT >> TSM GUI, I created a txt file with the absolute path like these 5:

C:\timesat31\NDVI\trial\ndvi_1
C:\timesat31\NDVI\trial\ndvi_2
C:\timesat31\NDVI\trial\ndvi_3
C:\timesat31\NDVI\trial\ndvi_4
C:\timesat31\NDVI\trial\ndvi_5


They belong to 1 year data. Number of Row 1461 Number of Col 2255

Row to process 500 to 500

Column to process 500 to 500

but I get a following warning:

Error while evaluating unicontrol Callback

Could anybody help me out?
