Correlation between two raster using band collection statistics

ShirleyLi — Wed, 12 Jul 2017 20:07:00 GMT

I'm using band collection statistics to calculate correlation between two kernel density rasters. But i got the following errors

ERROR 010007 : Too many arguments.usage: STACKSTATS <stack><out_data_file> {BRIEF | DETAIL}

ERROR 010067: Error in executing grid expression.

the two rasters have same cell size.

a little bit background: our goal is to see where two point distribution are similar or not similar. so i generate kernel density rasters from the two point layers, and run band collection statistics to calculate the correlation between the two rasters.

Any help is appreciated!

you don't indicate whether you are doing this through the tool or via a script

BandCollectionStats([inRasterBand1, inRasterBand2], outStatFile, "DETAILED")‍

the first parameter is a list of rasters, in a workspace or their absolute paths. Too many parameters suggests that the bands aren't enclosed in a list. If scripting isn't the case, show the dialog prior to running or show your script

Hi Dan,

Thank you for your quick response. I'm using the tool and attached is a screenshot of the tool settings. I entered the path of the two rasters and where the result txt will be stored. I also checked the "compute covariance and correlation matrices" option.

even with the paths scratched out, they appear very long, on some sort of network drive... can you not work on your local machine with a simple folder structure (c:\test for example) to try to rule out their location and path issues.

it works! i move them to a local folder with a shorter path and it ran successfully. Thank you!

That is good. My mottos... work local ...and ... the path to enlightenment is short and clean
