<p class="MsoNormal">Yes, you are absolutely correct. Thank you for reporting this issue. This is a bug that was introduced as part of the conversion to use Vital. We actually just discovered this bug a couple of weeks ago and made a fix in our internal
development branch that is pending public release approval. I had forgotten that this bug might also affect the public master branch. I have rebased our internal fix and pushed it to Github. The pull request is here:<o:p></o:p></p>

When I run maptk_bundle_adjust_tracks I get this error message:<br>

An older version of Map-TK which was used for the CVPR 2015 tutorial did not have this issue. I debugged the issue and I believe I tracked it down to this commit:<br>

Convert to use new vital without boost<br>
<br>
Convert use of boost file path to vital::path_t<br>
Use kwiversys support to replace boost file system calls<br>
<br>
It looks like the intent of this commit was to replace boost::filesystem::path::stem() which returns the filename without the path or last extension with kwiver::SystemTools::GetFilenameWithoutExtension() which does a similar function but instead replaced it
with kwiver::SystemTools::GetFilenamePath() which returns the path of the folder that contains the file but not the filename itself. Is this correct?<br>
<br>
I am going to attempt replacing the calls to kwiver::SystemTools::GetFilenamePath() with kwiver::SystemTools::GetFilenameWithoutExtension () and see if this fixes the issue.<br>
<br>
Thanks,<br>
<br>
