Detailed Description

Class which handles the communication between OpenMS and the Mascot server.

This class provides a communication interface which is able to query the Mascot server and reports the identifications provided be the Mascot server

Parameters of this class are:

NameTypeDefaultRestrictionsDescription
hostname string  Address of the host where Mascot listens, e.g. 'mascot-server' or '127.0.0.1'
host_port int80 min: 0Port where the Mascot server listens, 80 should be a good guess
server_path stringmascot  Path on the server where Mascot server listens, 'mascot' should be a good guess
timeout int1500 min: 0Timeout in seconds, after which the query is declared as failed.This is NOT the whole time the search takes, but the time in between two progress steps. Some Mascot servers freeze during this (unstable network etc) and idle forever, the connection is killed. Set this to 0 to disable timeout!
boundary stringGZWgAaYKjHFeUaLOLEIOMq  Boundary for the MIME section
use_proxy stringfalse true, falseFlag which enables the proxy usage for the HTTP requests, please specify at least 'proxy_host' and 'proxy_port'
proxy_host string  Host where the proxy server runs on
proxy_port int0 min: 0Port where the proxy server listens
proxy_username string  Login name for the proxy server, if needed
proxy_password string  Login password for the proxy server, if needed
login stringfalse true, falseFlag which should be set 'true' if Mascot security is enabled; also set 'username' and 'password' then.
username string  Name of the user if login is used (Mascot security must be enabled!)
password string  Password of the user if login is used (Mascot security must be enabled!)
use_ssl stringfalse true, falseFlag indicating whether you want to send requests to an HTTPS server or not (HTTP). Requires OpenSSL to be installed (see openssl.org)
export_params string_ignoreionsscorebelow=0&_sigthreshold=0.99&_showsubsets=1&show_same_sets=1&report=0&percolate=0&query_master=0  Adjustable export parameters (passed to Mascot's 'export_dat_2.pl' script). Generally only parameters that control which hits to export are safe to adjust/add. Many settings that govern what types of information to include are required by OpenMS and cannot be changed. Note that setting 'query_master' to 1 may lead to incorrect protein references for peptides.
skip_export stringfalse true, falseFor use with an external Mascot Percolator (via GenericWrapper): Run the Mascot search, but do not export the results. The output file produced by MascotAdapterOnline will contain only the Mascot search number.
batch_size int50000 min: 0Number of spectra processed in one batch by Mascot (default 50000)
