Model Server

Model Server is a tool for preprocessing and querying macromolecular structure data.

Installing and Running

Requires nodejs 8+.

From GitHub

git clone https://github.com/molstar/molstar
npm install

Afterwards, build the project source:

npm run build-tsc

and run the server by

node lib/commonjs/servers/model/server/server

From NPM

npm install --production molstar
./model-server 

(or node node_modules\.bin\model-server in Windows).

The NPM package contains all the tools mentioned here as "binaries":

• model-server
• model-server-query
• model-server-preprocess

Production use

In production it is required to use a service that will keep the server running, such as forever.js.

Memory issues

Sometimes nodejs might run into problems with memory. This is usually resolved by adding the --max-old-space-size=8192 parameter.

Preprocessor

The preprocessor application allows to add custom data to CIF files and/or convert CIF to BinaryCIF. node lib/commonjs/servers/model/preprocess or model-server-preprocess binary from the NPM package.

Local Mode

The server can be run in local/file based mode using node lib/commonjs/servers/model/query (model-server-query binary from the NPM package).

Custom Properties

This feature is still in development.

It is possible to provide property descriptors that transform data to internal representation and define how it should be exported into one or mode CIF categories. Examples of this are located in the mol-model-props module and are linked to the server in the config and servers/model/properties.
