Hello everyone,
Andrew York from Hari Shroff's lab recently released also an excellent open-source algorithm for 3D PALM, check it here or the publication here.
Cheers,
Ricardo

Ups, seams the links didn't go through. Here they are:

Hi Ricardo

I have a question about exactly how Quickpalm works, I'm not a phycist
by training so I apologise if this was discussed in your paper and I've
not quite understood it.

I've been setting up Palm imaging on a microscope system very similar to
yours. However I've been using biological specimens. I have already
corrected the images for drift and attach the results. As you can see
from the dataset attached I was trying to take some images of Eos-Actin.
Admittedly I didn't take perhaps as many frames as I should as the Andor
software was being fussy about data export but I'm still a bit confused
why the actin, which is in a filament, comes out dotty after analysis?
When I've looked at samples with punctate staining they look just fine.

Can I ask does Quickpalm work by looking for individual PSFs? If so when
you will have overlapping PSFs, such as in the actin filaments in my
sample, how does Quickpalm deal with that?

Thanks in advance for your advice.

Ann

Hi Ann,

How many images and particles are you detecting? Typically you would want to acquire >=20.000 images with 10-100 particles (PSFs) per frame, this would already allow you to start resolving the filaments on non-patchy matter.

If in trouble with the acquisition give a try to micro-manager, it saves directly to TIFF and I have no major issues with acquiring from 10.000 - 500.000 images in burst mode.

Cheers,
Ricardo
