cmake - Tried Normal Distributions Transform with my own files (in correct PCD format) and it throws errors, why? -

-

http://pointclouds.org/documentation/tutorials/normal_distributions_transform.php#normal-distributions-transform

i've used program sample pcd's given , came out correctly. confirmed experienced users on here. i'm trying use own pcd's. didn't want bother changing program changed names room_scan1 , room_scan2. when attempt use them, error:

loaded 307200 data points room_scan1.pcd loaded 307200 data points room_scan2.pcd filtered cloud contains 1186 data points room_scan2.pcd normal_distributions_transform: /build/buildd/pcl-1.7-1.7.1/kdtree/include/pcl/kdtree/impl/kdtree_flann.hpp:172: int pcl::kdtreeflann::radiussearch(const pointt&, double, std::vector&, std::vector&, unsigned int) const [with pointt = pcl::pointxyz, dist = flann::l2_simple]: assertion `point_representation_->isvalid (point) && "invalid (nan, inf) point coordinates given radiussearch!"' failed. aborted (core dumped)

this program compiled: http://robotica.unileon.es/mediawiki/index.php/pcl/openni_tutorial_1:_installing_and_testing#testing_.28openni_viewer.29

before suggest it, let know changed of pointxyzrgba designations pointxyz. threw same error before , after doing this. thing confuses me looked @ produced pcd files , seem same samples given ndt.
