[ptx] keypoints?

[Stefan M. Brandl]

Hello,
when I try to run panosifter I get:

smb at knatterpatrone:~/Bilder/Panoramas$ panosifter -o tester koez1_1.jpg koez1_2.jpg koez1_3.jpg koez1_4.jpg koez1_5.jpg koez1_6.jpg koez1_7.jpg koez1_8.jpg

The resulting tester1.pto has no control points.
What/where is keypoints?
