Calibration error

Postby CliveB » Wed Aug 13, 2008 1:54 pm

Hi all,

I have a problem when I try to calibrate ( avi, or manually) I keep getting the error:

" Number of 2d points (25) does not fit number of 3d points (0) "

Has anyone had this happen to them. I deleted the xml file thinking this would reset, but it does not work.
Can anyone help?

check your calibpoints.dat. If you `ve an empty file you`ll get this message.

Hope that helps

An other reason might be that DAVID does not find the calibpoints.dat file because the working directory was wrong. Did you get an error message after starting DAVID?

Calibration Error

Hi Simon, Gunter,

I unzipped the Calibration.dat file from version 2c and that seemed to do the job. It just seemed strange that it would go weird on me.

Thanks for you help
