Hello, I was trying to iterate through folder with rasters for some calculations between the bands of each one. I have a script that is stored in a toolbox and ask for couple of parameters. when I run the script, it makes the process for the first image but after that it does not works for the next one and the following error appears: I should mention that I tried the same but running the script as stand-alone using the python command promt and it works Then I tried something easy in the python window in ArcgisPRO: import arcpy from arcpy.sa import * from arcpy import env import os arcpy.env.workspace = 'C:\\Imagenes_Satelitales\\2018\\Junio\\Poligono3' arcpy.env.overwriteOutput = True LR = arcpy.ListSpatialReferences('*SR_clip*') LR ['20180607_145218_0f4e_3B_AnalyticMS_SR_clip.tif', '20180607_145219_0f4e_3B_AnalyticMS_SR_clip.tif', '20180607_145220_0f4e_3B_AnalyticMS_SR_clip.tif'] for raster in LR: #getting bands Image = Raster(raster) b3 = Image.getRasterBands()[2] b4 = Image.getRasterBands()[3] result = arcpy.sa.Float(b4 - b3) name = os.path.splitext(raster)[0] result.save(os.path.join('C:\\Imagenes_Satelitales\\2018\\Junio\\Poligono3', name + 'result.tif') Traceback (most recent call last): File "<string>", line 3, in <module> File "c:\program files\arcgis\pro\Resources\arcpy\arcpy\sa\Raster.py", line 79, in __new__ return super().__new__(cls, in_raster, is_multidimensional) RuntimeError: ERROR 000732: Input Raster: Dataset 20180607_145218_0f4e_3B_AnalyticMS_SR_clip.tif does not exist or is not supported That type of error is the same that I got when I run the complete script. For now, I am going to continue using the python command promt for running the script but I would like to do it from the toolbox that I have for that purpose. Thanks, Jhon Eric
