27// MDataSet
28//
29// This class describes a collection of sequences.
30//
31// Such an input file looks like:
32//
33// crab.seq:
34// ---------
35// AnalysisNumber: 1
36//
37// SequencesOn: 35222
38// SequencesOff: 36817
39//
40// Sequence00035222.File: sequences/sequence035222.txt
41// Sequence00036817.File: sequences/sequence036817.txt
42//
43// Sequence00035222.Dir: /data2/wuerzburg/Crab-Analyse/images/035222
44// Sequence00036817.Dir: /data2/wuerzburg/Crab-Analyse/images/036817
45//
46// The analysis number is an artifical number used to name the output
47// files automatically if the names are not overwritten in the corresponding
48// programs.
49//
50// The sequence number are used to concatenate the filenames of the
51// sequences using the file structure used in the datacenter.
52//
53// If you have different file names you can overwrite the default file names
54// using Sequence%08d.File (make sure you have 8 digits!)
55//
56// In standard coditions (datacenter file system) paths are concatenated
57// by using the information in the sequence files (date, etc). You can
58// overwrite the directories in which the sequence-files (eg I-files) are
59// stored using Sequence%08d.Dir (make sure you have 8 digits!)
60//
61// Resource file entries are case sensitive!
62//
63// MISSING (27/01/04): The default name and paths cannot be used yet, because
64// they have to be defined soon.
