Error in getting RMS output file with Trend analysis (ArcGIS Pro)

[Shwarnali]

I am experiencing errors when I am trying to obtain surface trends with RMS output file in ArcGIS Pro Spatial Analyst tool.  However, there is no problem obtaining trend raster without RMS outfile file. Howe can I solve the issue?

Here is the following error:

Try a different folder than ... E:\Project6.2\rms2.TXT

punctuation in file paths can cause issues.

But you might want to specify your inputs, if this is the tool you are using

I was also having the same issue, I had space in the file path.

Solution - The path of the text file should not have any spaces or punctuation.
