Export transect pixel option is disabled

Hello All,

I am trying to use the “export tansect pixel” option on SNAP desktop application. But this option is disabled. I tried to use it by selecting a rectangular area in one of the bands -> right-click->export transect pixel. I get the error saying “No transect defined in the selected band”.
I also tried in from the tool bar-> raster -> export transect pixel. This was disabled.

Thanks in advance!

transect indicates a line, did you also check with a line feature? Sometimes it is good to save the product after digitizing geometries first so they are really written into the product.
