Hi guys,

I have a table where the row IDs are like this:

ABCDEF-1.tiff

ABCDEF-1.tiff_1

ABCDEF-2.tiff

ABCDEF-2.tiff_1

...

What I did not manage to do yet is to filter out every second row. I tried with regular expressions but I could not get it to work ...

I only need all rows ending with *.tiff for the other processing steps. Any help is really apprciated.

Use "row filter" node

Select "regular expresion" and use this expresion:

(.+)(\.tiff)
