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:

Name	Type	Default	Restrictions	Description
hostname	string			Address of the host where Mascot listens, e.g. 'mascot-server' or '127.0.0.1'
host_port	int	80	min: 0	Port where the Mascot server listens, 80 should be a good guess
server_path	string	mascot		Path on the server where Mascot server listens, 'mascot' should be a good guess
timeout	int	1500	min: 0	Timeout 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	string	GZWgAaYKjHFeUaLOLEIOMq		Boundary for the MIME section
use_proxy	string	false	true, false	Flag 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	int	0	min: 0	Port 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	string	false	true, false	Flag 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	string	false	true, false	Flag 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	string	false	true, false	For 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.

If a section name is documented, the documentation is displayed as tooltip.
Advanced parameter names are italic.
