Cascade classifier can't be trained. Check the used training parameters - opencv

Question

I need to detect special image (something like symbol +) in scanned document. I'm going to train cascade using opencv_traincascade program (opencv 3.0)
This is my file structure:
C:\imgs\learn1
Bad
1.bmp
....
Good
1.bmp
....
Bad.dat
Good.dat
This my Bad.dat:
Bad\1.bmp
...
Bad\53.bmp
Bad\img001.jpg
...
Bad\img146.jpg
This is my Good.dat (every good file fully contains the special image and nothing more)
Good\1.bmp 1 0 0 60 59
...
Good\100.bmp 1 0 0 27 28
I've successfuly created vec file.
C:\opencv\build\x64\vc12\bin>opencv_createsamples.exe
-info C:\imgs\learn1\Good.dat
-vec samples.vec
-w 10 -h 10
Info file name: C:\imgs\learn1\Good.dat
Img file name: (NULL)
Vec file name: samples.vec
BG file name: (NULL)
Num: 1000
BG color: 0

Invert: FALSE
Max intensity deviation: 40
Max x angle: 1.1

Create training samples from images collection...

Train dataset for temp stage can not be filled. Branch training terminated.
Cascade classifier can't be trained. Check the used training parameters.
As you can see, there is some error. Can you help me what is wrong exactly? "Check the used training parameters" is very general phrase.
(The folder C:\opencv\build\x64\vc12\bin\haarcascade exists)

Answer 1

I don't know what was wrong, but I've done it.
1)I've increased number of positive examples to 400
2)I've increased number of negative examples to 398
3)I found that if an image size 61 x 60, I shoud write in Good.dat
Good\1.bmp 1 0 0 60 59
(Image coordinates begin from 0 and end at width-1 and height-1 values)
4)I found type error: minhiteate - > minHitRate
and nothing helps...
5)I try to train in openvc 2.4 and i've got my cascade.xml file
But now I can't use it because of other error, but it's offtopic. (now I,m googling)
