NAME
Finnigan::ScanParameters -- a decoder for ScanParameters, a GenericRecord containing various scan meta-data.
SYNOPSIS
use Finnigan;
my $p = Finnigan::ScanParameters->decode(\*INPUT, $generic_header_ref);
say $p->charge_state;DESCRIPTION
This decoder augments the GenericRecord decoder with the charge_state method. Copies of all other elements in this structure can be found in other streams, so there is no need in making accessors for them. The purpose of this stream is to provide pre-formatted human-readable messages describing the scan data; The charge_state element seems to be unique in that it either does not exist anywhere else, or has not been discovered so far.
The entire set can be printed in the following manner:
foreach my $key (@{$header->labels}) {
say $key . "\t" . $p->{data}->{$key}->{value};
}METHODS
- decode($stream, $header->field_templates)
-
The constructor method. It needs a previously decoded header to work.
