Datasets: properties and methods

Introduction

Datasets are a collection of MSscans that described the separation and aquisition. The Finnee object can hold many datasets, while the first dataset will be made by the recording of the MS scans as a function time, Finnee allows manipulating the data in order to improve the quality of information. Each transformation will be recorded in a new dataset.

General Properties

• .Title Self-explanatory
• .Log A recording of all transformations that were done to obtain this dataset
• .DateOfCreation Self explanatory
• .Format Format of the MS scans (centroid' or 'profile'
• .BPP A Trace object, the base peak profile; the maximum intensity of each MS scan
• .TIP A Trace object, the total ion profile; the sum intensity of each MS scans
• .TIS A Trace object, the total ion spectrum; only available if a common m/z axis exists. The sum of all MS scan
• .FIS A Trace object, the frequency ion spectrum; only available if a common m/z axis exists. The number of non-zero values at every m/z increment.
• .BIS A Trace object, the base iso spectrum; only available if a common m/z axis exist., the maximum intensity at every m/z increment.
• .LAST A blank Trace object
• .ListOfScans An array of Trace Object. The MS scans.
• .Options4crt Information on the function used to create the dataset
• .Path2Dat The list of all dat files linked to the Trace objects.
• .AxisX Information about the x-axis (label, unit precision, and data for the axis)
• .AxisY Information about the y-axis (label, unit precision and data for teh axis)
• .AxisZ Information about the z-axis (label, unit precision)
• .tol4MZ m/z tolerance
• .MZLim a 2x1 array with the lowest m/z value and highest m/z value
• .Path2Fin Full path to the Finnee object
• .AddInfo A structure used to store additional information
