Hi Shiras,

We found that bug recently with Sebastien Brousmiche and fixed it, at least for the use case we were considering. Can you try with the git master version of RTK ?
Alternatively, you can replace

reader->Update()

with

reader->UpdateOutputInformation()

in line 61 of rtkramp.cxx and see if it fixes the problem.

Regards,
Cyril

Dear all,

When I use rtkramp with cuda option, I am getting following error

However, cpu version of ramp filter works fine.

Thanks in advance.
