I/O File Format

In the curve fitting analysis, you may need to input massive test data. To facilitate your data editing, CurveFit provides you convenient data import and export tools. This section depicts the file format used in the CurveFitter import/export processes.

For the test data, you can import/export the data from/to external files in two types of formats: plain text and Excel files. Both formats share a similar schema. The details of each format are discussed below.

  • The comment line starts with ### symbol and will be ignored by the reader.
  • The first row lists the quantity names.
  • The second row shows the units. CurveFitter does not support units, thus put dash symbol - for each quantity.
  • The third row gives the dependency of the quantity. Only two options: independent, dependent. For the subtable data, this entry shows two independent keywords.
  • The kernel test data start from the fourth row. The columns of data need to match that of quantity names.

Note

In the sub-table data file, ie. Core Loss test data, you will see duplicated values in the first column in representing the pivotal value for the subtable data.

Plain Text Format
