Bioinformatics Series: Cytoscape and Chimera
CLASS LEVEL
Intermediate
PREREQUISITE
Please see individual class descriptions below.
You may attend any number of classes in this series. Classes are free, but you must sign up.
Molecular Visualization with UCSF Chimera: Getting Started
This session will go over the basics of molecular visualization
and provide an introduction to how to use UCSF Chimera to load,
visualize, and manipulate protein structures. Topics include: installing Chimera; Chimera menus and commands;
fetching protein structures from ModBase and PDB; selections and actions; depictions; key tools: Side View, Model Panel, and the Selection Panel; and saving your work: sessions and images.
Participants should have a basic understanding of protein structure.
All participants will receive a CD with UCSF Chimera installers for
Mac, PC, and Linux as well as example files and additional exercises.
Molecular Visualization with UCSF Chimera: Basic Tools
This session will cover general structure visualization and analysis with
Chimera. Topics include: identifying hydrogen bonds and contacts; measuring distances and angles,
rotating bonds; viewing amino acid sidechain rotamers, "mutating" residues; displaying attributes
such as B-factor and residue hydrophobicity; superimposing and comparing structures, morphing; viewing
NMR ensembles and molecular dynamics trajectories.
Participants should have an acquaintance with molecular graphics
and protein structure, although expertise with Chimera is not required.
Participants are encouraged to bring structures of interest (or note
their Protein Data Bank IDs for retrieval in the lab) as "real-life"
examples to supplement the exercises that will be provided.
Exploring Sequence-Structure Relationships with UCSF Chimera
This session will cover working with protein sequence alignments together
with 3D structures. Topics include: Web resources for protein family sequence alignments;
sequence-structure association and crosstalk; calculating alignment conservation and displaying it on structures;
using the alignment to match (superimpose) structures; matching structures without a pre-existing alignment; creating sequence alignments from multiple structure superpositions; customizing alignment appearance in Chimera; editing and saving.
Participants should have at least a little experience with Chimera and
a basic understanding of protein structure and sequence alignments. Participants are encouraged
to bring data on systems of interest (structure IDs, and if available, corresponding sequence alignments)
as "real-life" examples to supplement the exercises that will be provided.
Working with EM and X-ray Density Maps in UCSF Chimera
This session offers hands-on training for studying density maps,
especially those from electron microscopy. You'll look at maps of
phage K1E, a virus that infects E. coli, and learn to segment the
protein coat from the packaged DNA genome, color to distinguish virus
surface structures, morph to compare related viruses, and fit atomic
models into the maps. The same techniques are applicable for
crystallographic and tomographic density maps.
Participants should have familiarity with Chimera.
Publication-Quality Images and Movies with UCSF Chimera
This session provides hands-on training for creating images and movies
of molecular models and density maps for journal articles and
presentations. You'll be introduced to the myriad of options to
enhance your graphics: raytracing, depth cueing, supersampling, ribbon
styles, silhouette edges, subdivision level, text labels, clipping and
capping, transparent or colored backgrounds, fish eye views, presets,
lighting, shininess, ambient occlusion, lenticular images, and movie
transitions and encoding. You'll try these techniques on your own data
(downloaded or brought on a flash drive or CD) or using example data
we provide.
Participants should have familiarity with Chimera.
Customizing and Tailoring UCSF Chimera
This session will cover methods for customizing Chimera for specific
tasks and projects. Topics include: writing command and demonstration scripts; accessing Chimera
data structures using Python; adding per-frame actions for analyzing molecular dynamics;
adding user-defined headers to sequence alignment displays; adding your own user interface elements to Chimera.
Participants should have hands-on experience with Chimera. If there
is a topic of particular interest, please mention it at the beginning
of the session (or contact us beforehand) to ensure that we allot sufficient time to go into details.
Exploring Protein Similarity Networks with Cytoscape, UCSF Chimera, and SFLD
This session will cover the tools and methods that have been developed
at UCSF to explore protein similarity networks. A protein similarity
network is a network of nodes and edges where the nodes represent the
protein and the edges represent some measure of the similarity between the proteins.
These networks have been used to infer functional and evolutionary
relationships between proteins and protein families. Session topics
include: overview of protein similarity networks; using SFLDLoader to import protein similarity networks into Cytoscape; Cytoscape layouts suitable for protein similarity networks; exploring structural relationships with structureViz; creating your own protein similarity network; adding structural annotation to an existing protein similarity network.
Participants should be familiar with Cytoscape and have some experience
with molecular structure visualization.
