gps coordinates with txt.

[Caesar B]

GOODBYE TO ALL, I WOULD LIKE TO IMPORT GPS COORDINATES IN VSFM, AND DO NOT USE THE COORDINATES PRESENT IN THE EXIF ​​OF THE PHOTOS.
I CREATED A TXT. WITH INSIDE THE COORDINATES, BUT, VSF WITH THE CTRL + BASED TRASFORM COMMAND ... SAYS ..
0 GPS coordinates found for the current model
ERROR: Not enough GPS coordinates ..
what could be the mistake?
how do you write the txt file?
I wrote it like this ..
