Hello,
I have been trying to composite 3 bands and keep getting this error message:
ExecuteError: ERROR 000271: Cannot open the input datasets
Failed to execute (CompositeBands).
I have run several small tests to see if my names were OK - they seem to be.
I have also tried compositing tiffs, grids in a folder and grids in a file geodatabase. I get the message every time. I don't see anything in the CompositeBands description that indicates my parameters are off.
Do any of you have some ideas?
Here is the code:
Maybe there's a work-around?
Thanks for any insight.
Kat
edit: I forgot to say that I am using ArcGIS 10.0 sp1 and that I am running the script as a stand-alone.
Also, I am using Python (IDLE) 2.6.5

Here is the code:
Code:
()
#import system modules
import arcpy, os
from arcpy import env
arcpy.env.workspace = r"C:/FINAL/data.gdb"
#overwrite files with the same name
env.overwriteOutput = True
#list the rasters to be used
#rasters in the geodatabase that start with 't' are 4-band images
rasters= arcpy.ListDatasets("t*", "Raster")
#rasters that start with ,p, are 4-band PCA results
PCA= arcpy.ListDatasets("p*", "Raster")
#make a combination of bands 1,4 and 2nd PC
for raster in rasters:
raster1= raster + "/Band_1"
raster4= raster + "/Band_4"
r_index= raster[1] + raster[3]
for component in PCA:
p2= (component, "/Band_2")
print "processing: " + r_index
outRaster = ("b14p" + r_index)
if r_index == component[1:3]:
arcpy.CompositeBands_management("raster1; raster4; p2", outRaster)
print "Composites complete"
#Thanks for any insight.
