PCA Node Empty Columns

Hi all,

I am battling with the PCA node. Although the data table is correct in the previous node, the PCA dialog box does not have any columns to select.

What am I doing wrong?

Welcome to the forum, @kolorhari.

You really haven’t given us much to work with. It would be best if you provided your workflow and some sample data.

Although the data table is correct in the previous node

What does this mean, exactly?

Hi @kolorhari and welcome to the forum.

This is purely a guess, but perhaps the table you are feeding to the PCA node consists only of strings? In that case, you should convert to numbers first.
