NAME

Finnigan::RawFileInfoPreamble -- a decoder for RawFileInfoPreamble, the binary data part of RawFileInfo

SYNOPSIS

  use Finnigan;
  my $file_info = Finnigan::RawFileInfo->decode(\*INPUT);
  say $file_info->preamble->run_header_addr;
  say $file_info->preamble->data_addr;
  $file_info->preamble->dump;

DESCRIPTION

This this object decodes the binary preamble to RawFileInfo, which contains an unpacked representation of a UTC date (apparently, the file creation date), a set of unknown numbers, and most importantly, the more modern versions of this structure contain the pointers to the ScanDataPacket stream and to RunHeader, which stores the pointers to all other data streams in the file.

The older versions of this structure did not contain anything except the date stamp.
