Hi,<br>
I recently added the --subsetsize option (see <a
href="https://github.com/SimonRit/RTK/commit/b78bd03f38a6944448b77a683a0c1d69857b439d">this
commit</a>). You can try "--subsetsize 1" instead of using
rtksubselect.<br>

Hi Shiras,<br>
<br>
<br>
<br>
Another user had the same error some years ago : <br>
<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://public.kitware.com/pipermail/rtk-users/2012-November/000028.html">http://public.kitware.com/pipermail/rtk-users/2012-November/000028.html</a><br>
<br>
It seemed to be a GPU memory size issue.<br>
<br>
<br>
<br>
Can you tell what GPU you use, are what are the size and number of<br>
your projections ? Can you try with a single projection (you can
use<br>
the "rtksubselect" application to create such a dataset out of<br>
yours) ? <br>
<br>
<br>
<br>
Best regards,<br>
<br>
Cyril<br>

<div>Thanks a lot. Now rtkramp.exe works with cuda option.</div>

<br>
<br>
<br>
We found that bug recently with Sebastien Brousmiche and<br>
fixed it, at least for the use case we were considering.<br>
Can you try with the git master version of RTK ?<br>
<br>
Alternatively, you can replace <br>
<br>
<br>
<br>
reader->Update()<br>
<br>
<br>
<br>
with <br>
<br>
<br>
<br>
reader->UpdateOutputInformation()<br>
<br>
<br>
<br>
in line 61 of rtkramp.cxx and see if it fixes the
problem.<br>
<br>
<br>
<br>
Regards,<br>
<br>
