I am using gmapping and it is working fine with fake odometry.

But now I wanted to use laserscanmatcher to get better odometry data. when ı used laserscanmatcher with demo launch also it use a demo bag file , no problem it is succesfull. but when ı used to own laser bag file or used real laser data, laserscanmatcher throw this error :

Strange FOV: -6.283185 rad = -360.000010 deg 
[ WARN] [1435132671.572614765]: Error in scan matching****

I am using static tf for laser to base_link.
