IPF2ISG - Forum - iMOD

Hi,

I want to convert a IPF file to an ISG in order to import river data into imod. When I load the converted ISG into imod, the geometry shows and i can use the "ISG show..." options to let me examine the stream direction and such. However, as soon as I select "ISG edit", imod crashes completely. After checking the IPF file, I am pretty sure, that it is in the correct format. Below, I inserted the batch function as well as the header and the first rows of the IPF. Maybe I made a mistake in this part already?
In case you need the whole dataset to reproduce the error let me know.
Has anyone run into a similar issue and/or can help me out?

FUNCTION=IPF2ISG
IPFFILE=C:\Users\Kristina\Documents\hlnug\qgis\gewaesser.ipf
ISGFILE=C:\Users\Kristina\Documents\hlnug\qgis\gewaesser.isg
