[phenixbb] Re: cryo em map

Hi Tim, It looks like you’ll need to navigate a bit of a learning curve using the available online resources (rather than me re-typing everything here!). Here are some useful pointers: 1) Phenix Video Tutorials: https://www.youtube.com/c/phenixtutorials There are several relevant tutorials on model building. 2) Self-Guided Tutorials: Phenix comes with built-in tutorials, including many focused on model building. You’ll see examples of how to use them in the video tutorials mentioned above. 3) Phenix Documentation: https://phenix-online.org/documentation/ It provides plenty of detailed guidance and references. 4) Workshops for Hands-On Experience. Consider attending one of upcoming workshops with Phenix experts: - ACA Satellite Phenix Workshop (Summer 2025); - Week-long Crystallography & Cryo-EM School in Madrid (Spring 2025); - Mini Phenix Workshop at the West Coast Structural Biology Meeting (Spring 2025); ...and I’m sure more will be coming in 2025. Please reach out if you have specific questions that aren’t covered in these resources. Good luck! Pavel On 12/18/24 09:49, tim smith wrote:

Hi all,

Can you please advise once we fit the map and open in coot. What is next step to do in coot. I tried refmac but that required ccp4 file which doesn't have. Please some one can help in elaborating and sharing any tutorial would be helpful. I'm new bie and first time I am trying model building. Any help would be really appreciated. Thank you so much Best wishes Tim

Hello Iram,

The general workflow for Cryo-EM is described here: https://phenix-online.org/documentation/overviews/cryo-em_index.html

It looks like you are ready to refine your model, so the tool for it is phenix.real_space_refine: https://phenix-online.org/documentation/reference/real_space_refine.html that also has a video tutorial.

Let us know if you have any questions.

Best regards, Oleg Sobolev.

Hello All.       I got a nice 2.45 Angstrom map from cryo em data. I checked handedness, map model fitting on the chimera and opened in the coot. It looks nice. Can you please give me suggestions about the Phenix refinement steps.
