The ASCII data file format is the most commonly used file format for measurement files. It is a general text format that can be imported e.g. into Microsoft Excel or MATLABTM (MathWorks Inc). It is the similar way MATLABTM stores a data matrix in an ASCII file.
The measurements of a specific transducer are stored as a single column in the ASCII file. So the data in the ASCII file can be interpreted as a matrix whose columns are the different transducers and the rows the measurements of these.
An example (Examples Folder: \Building Model\Mes31set.asc) of a data file is shown below:
In this case there are four columns corresponding to four transducers and rows which corresponds to the samples of the transducers. The measurements of the first transducer is column number 1 from the left.
The following should noted:
All transducers must have the same number of samples.
There can be other information in the beginning of the file, such as a header.
Formatting such as scientific or fixed formats are allowed.
The delimiters between the samples should be either blank spaces or tabs.
