issues with computing photon counts by exponential distributions

Fitting exponential distributions to molecule areas output from insight, multiplied by photon per count for gain 30  on STORM2 (.41 photons).       These data are all from Hazen’s 2D microtubules.  My 3D microtubules, Yari’s 2D sections, my 2D … Continue reading

chromatic warp issues

warped image blurs out certain channels.  here 561 gets stretched along x. In the K27/K4 dataset 750 is dramatically stretched along x-y in a correlated fashion. Distortions get worse using higher order polynomial (e.g. 4th order).   Distortions are no … Continue reading

Compare 2D and 3D spot finding results

2D in green, 3D in red (H3-647).   Z images are collapsed down into single plane.  It looks like brightness differences are substantial, better contrast total photons from 2D imaging (might have expected reverse, 3D apparently doesn’t compensate for photon … Continue reading
