LVE: General Description

Purpose

Data Files

  • The first line of the file should contain the sample parameters separated by semi-colons (;). It may contain any number of parameters which will be read and saved as file-parameter in RepTate. In unit-aware applications, a file parameter value may also include an explicit unit, for example Mw=1131 Da;T=25 ºC;gdot=0.1 1/s;.

  • Then the data columns should appear, separated by spaces or tabs.

  • In unit-aware applications, column headers may include units in square brackets or parentheses, for example t [min] or G' [kPa]. See Units for the supported units and current limitations.

.tts extension

Text files with .tts extension should be organised as follows:

  • .tts files should contain at least the parameter values for the:

    1. sample molar mass Mw,

    2. temperature T.

  • 3 columns separated by spaces or tabs containing respectively:

    1. frequency, \(\omega\),

    2. elastic modulus, \(G'\),

    3. loss modulus \(G''\).

Other columns will be ignored. A correct .tts file looks like:

T=-35;CTg=14.65;dx12=0;isof=true;Mw=13.5;chem=PI;PDI=1.04;
