Hello,I am trying to join the results of an external model (.txt) to a raster produced from another process and then export that raster to a new file. I've been trying to use TabletoDBase or TabletoTable to convert the .txt to a .dbf to do the join. The former works, but my primary problem is that even though one of my fields in the .txt is a double, it gets converted to an integer in the .dbf. Worse, is that this only happens sometimes. The first record happens to have a 1 in that field, so I'm wondering if the TabletoDBF tries to guess the datatype from the first record. By the way, I'm on ArcGIS 10.1 and Python 2.7.So, my questions is:1. What is the best overall flow for joining a .txt to a raster and saving it to a new raster?2. I am also having overwrite issues. What is the best approach for checking if a file already exists and then deleting it before running the code?3. Any other tips would be much appreciated. You'll see from my code that I'm a rookie. Please go easy on me!Thanks for your help.# Set environment settings

## 1. Convert Netica output .txt file to .dbf
# Set local variables
inTable = askopenfilename(parent=root, initialdir=env.workspace, title='Please select a Netica output file') # show an "Open" dialog box and return the path to the selected file
outDBF = inTable[:-4] + ".dbf"
outLocation = env.workspace
try:
# Execute TableToDBASE
arcpy.TableToDBASE_conversion(inTable, outLocation)
#arcpy.TableToTable_conversion(inTable, outLocation, outDBF)
except:
print arcpy.GetMessages()
## 2. Join composite raster from GDB_to_Netica with .dbf from step 1 above and export it to new raster.
# Set local variables
inRaster = askopenfilename(parent=root, initialdir=env.workspace, title='Please select the combined raster file') # show an "Open" dialog box and return the path to the selected file
layerName = "RstTMP"
joinTable = outDBF
joinField1 = "Value"
joinField2 = "IDNum"
outRaster = whichmodel + "_SUIT_" + env.workspace[-8:] + ".tif"
outRaster2 = gdbDir + outRaster
# Create a feature layer from the vegtype featureclass and add index to joinField1
arcpy.MakeRasterLayer_management (inRaster, layerName)
arcpy.AddIndex_management (layerName, "Value", "Index", "NON_UNIQUE", "NON_ASCENDING")
# Join the feature layer to a table
arcpy.AddJoin_management(layerName, joinField1, joinTable, joinField2, "KEEP_COMMON")
# Copy the layer to a new permanent feature class
arcpy.CopyRaster_management(layerName, outRaster)
# Copy this suitability raster to the appropriate GDB -------DOESN'T WORK 10.24.12
#arcpy.Copy_management(env.workspace + "/" + outRaster, outRaster2, "RasterDataset")
