Dear Developers,
1. RANSAC alignment:
Dear Dr. Sandra, your recommendation for the RANSAC alignment worked little
better with alignment for at least 50% of the peaks . However, still I am not
getting correct alignment for all the peaks.
Kindly explain about the parameter "threshold value". With
Dear Developers,I am not able to do proper alignment using RANSAC. Same
peak is detected more than 2-3 times with in different rows, even though m/z
values(0.01 0r 5 ppm) and RT (1.00 min) are within in the threshold values. Can you please help me in setting up parameters?I used centroid for

Dear Developers,
Greetings!
To align 20 samples, I used following parameters in RANSAC
m/z tolerance=0.02 or 25 ppm
RT tolerance=1.5 min
RT tolerance after correction= 1.00 min
RANSAC iterations= 2000
Min no of points 30
