NCCAT Hardware (1/2020)¶

This is still being built and will support

1 x Hitatchi HT7800
1 x TFS Glacios with Ceta-D
3 x TFS Krios with Ceta, and Gatan K3
1 x TFS Krios with Falcon 4

All microscopes use Leginon for data collection and Appion for preprocessing (defined as frame alignment/ctf estimation/particle picking) and on the same database server and together has ? web servers to serve the images for users to view and/or as Appion gui to construct the preprocessing commands. What is listed does not include infrastructure for 2D/3D classification and other post-processing.

Network¶

All hardware mentioned below as well as the instruments are on a local 10 GB copper network.
