hi

I was trying to train cascade using opencv_traincascade binary, I am using linux 3.7 I threw the below command opencv_traincascade -data imgs/cascade/ -numPos 200 -numNeg 8 -numStages 10 -featureType LBP -maxFalseAlarmRate 0.9 -w 640 -h 480 -vec imgs/vector.vec -bg negatve.dat

but it is giving me error "Image reader can not be created from -vec imgs/vector.vec and -bg negatve.dat."

I wanted to verify my vector file and background file, I dont know how to do it.

Thanks Anshul
