Data can be imported into MultiSens Analyzer in a number of different formats.
To import a file with measurement data into MultiSens Analyzer follow these steps:
- Create a new evaluation (e.g. Classification) by selecting "File->New->Classification" from the menu.
- On the "Reference Data" tab click on "Add".
- In the Open dialog choose the import format, e.g. "Text file (*.txt, *.dat, *.asc) format.
- Select the file and click on "Open"
A simple text file
The easiest format is probably the text format. Here is an example of how a the most simple text file for import into MultiSens Analyzer would look like:
It consists of a single line containing the word DAT and subsequently an array of data, with the sensors in the columns and the acquisitions in the row. For each measurement/sample that has been measured, an individual file needs to be created.
DATA
1.23 4.54 2.15 3.29 2.78 2.96 3.01 3.45 4.89 2.22 5.23 3.08 5.21 3.87 3.68 5.12
A more elaborate example
The following example also contains information about the sensors, the device used, the sample and the date, as well as parameters used during the acquisition.
#The text file always starts with a header that allows to describe #the measurement system, the sample, date and parameters.
#Only one measurement can be included in one text file.
#For each measurement you will have to create an independent text file.
#Remarks start with an "#" sign. MultiSens Analyzer will ignore these lines.
#Lines can be left empty
#The next line describes the sample:
Sample = Apple Juice
#The next line contains the source of the sample
Source = Crop 123
#Date contains the measurement date (and time) of the measurement.
#This data is imported using the language / date and time settings of Windows!
Date = 2.2.2009 12:20:02
#Device describes the instrument that has been used in the measurement
Device = JLMQ
#Sensors contains a list of the sensors, that are installed in the device.
#Sensors are separated by a space.
Sensors = QMB1 QMB2 QMB3 QMB4
#Next we add a number of parameters, that were used during the measurement
#MultiSens Analyzer will read the parameters, and store them within the evaluation
Acquisition interval = 1
Chamber temperature = 5
#The measurement data from the sensors is contained in an array,
#with the sensors in the columns and subsequent acquisitions in the rows.
#The individual values have to be formated as integers or floating points
#with a point "." as decimal separator.
#A space or tab should separate the values in a line
#The measurement data starts with the word DATA in a line
