feature request: opening particles from single tomogram

[jmdobbs]

Hi,

ArtiaX is really nice, but there are two things that seem (hopefully) easy enough to implement that would massively help the user experience. First, and most importantly, being able to display only the particles from one tomogram (with eg. the tomo ID in rlnMicrographName) when opening a star file.

Second, the ability to add custom color palettes would be very very nice.

If possible, it would be awesome to see these things (or at least #1) implemented :)

Thanks for the great software.

Hi Joe,

I also wanted to use the same thing today, and I found a workaround to be able to use the micrograph name as a selector.

So basically, instead of rlnMicrographName ArtiaX reads them as rlnTomoName (see

ArtiaX/src/io/RELION/RELIONParticleData.py

Line 87 in c741a63

'rlnTomoName': [],

).

So if you modify your starfile 'sed -i "s#rlnMicrographName#rlnTomoName#" your_filename.star', you will be able to select by micrograph/tomogram.

Still, it's going to be a slider selector like the other selectors (it would be really nice to have this as a dropdown menu for this specific one), but it should already be way easier than having to split your starfile by tomogram.
Another option is to make a fork and change this line to rlnMicrographName if you don't want to do this every time.

Hope it helps you and others!

Best,
Higor
PS. Btw, thanks a lot to the devs for this amazing tool!

Hey Higor,

That is indeed a nice workaround! I second your suggestion about the dropdown menu as well :)

Best,
Joe.
