Error - While running Create Confusion Matrix.

[JanakiGattu1]

Dear Team,

I tried doing the Image Classification Process - Got stuck when running the "Compute Confusion Matrix" after generating Random Points for Accuracy Assessment for Image Classification.

I am getting a message as below.

WARNING 001790: Not all points have valid class values.
ERROR 001094: Invalid file extension. The "" file extension is used for an ArcGIS dataset.
ERROR 999999: Error executing function.
Failed to execute (ComputeConfusionMatrix).

Hello, did you ever solve this? I have a student with the same issue. Thanks!

I just solved it! Seems that I had troubles saving the file in a folder I had to specify. But apparently, if we just write the name in the box, it will automatically create a table. Same way at this tutorial https://www.youtube.com/watch?v=Ya7rbzGl8hM, 3:30 min.

And also a short name can help a lot!
