Project definition and data input.
Project Name: choose a name. If not, a name will be generated from the datafiles selected below.
Predefined File Formats: a few data file formats have been predefined from the datafiles of different experiments. Choose the one corresponding to your data. For fine tuning, select ‘Other…’ which will open a new panel.
| Header | Separator | Decimal | Data structure | |
|---|---|---|---|---|
| CSV | FALSE | ‘,’ | ‘.’ | wxd |
| ELYSE | FALSE | ‘\t’ | ‘.’ | wxd |
| Fluo | FALSE | ‘;’ | ‘.’ | wxd |
| Streak | TRUE | ‘,’ | ‘.’ | wxd |
Header: does the first line contain column headers ?
Separator: symbol used to separate the columns
Decimal: character used in the file for decimal points
Data structure:
wxd: wavelength in columns; delays in lines
dxw: delays in columns; wavelengths in lines
Note: the first line of the matrix must contain the delays or wavelengths, depending on the choice of Data structure.
Example of a CSV-type data file structure
'x/y', t1, t2, t3, t4, ...
wl1, x11, x12, x13, x14, ...
wl2, x21, x22, x23, x24, ...
...Load-time compression factors: the data can be averaged by blocks at load time to save processing time and reduce noise.
Delay width (in pixels) of the block in delay dimension
Wavl width (in pixels) of the block in wavelength dimension
Transform delay (for single matrix only): when multiple files are assembled (tiled) the delay scale is replaced by an index in the plots to keep an increasing value. When a single matrix is downloaded, the original delay scale is preserved. This can be overridden by choosing either an index scale or a Log10 scale. In the latter case, all data points with null or negative delays are recasted uniformly in the interval \(]0, d_{min}[\), where \(d_{min}\) is the smallest positive delay.
Select data file(s): select one or several files to be analyzed. Selecting the files will create new items in the right panel:
a success message ‘Data Loaded !’
an active table with a description of the file(s). When several files have been loaded:
it is possible to use the table to select a subset or to reorder them.
a menu appears with processing options:
Average: average the selected files
Tile Wavl: assemble the matrices in the wavelength dimension
Tile Delay (default): assemble the matrices in the delay dimension. In this case, the delay coordinate is replaced by an index.

Post-process compression factor: the block averaging is performed after the data files are assembled.
