If the file does not have a header and you want to start importing at the first point in the file, leave the File Offset set to 0 (the default). If there is a header, or if you want to skip over some of the data at the beginning of the file, set this parameter to the number of lines to skip (for ASCII data files) or the number of bytes to skip (for binary data files).
Enter the number of columns or channels in the data file. If there are multiple columns in the file, you will need to import each column individually. The default number of columns is 1.
Indicate which column or channel in the file you want to import into the Dataset and Series you have specified in the Import Data dialog box. If there are multiple channels in the file, you will need to import each channel individually. The default number of columns is 1.
Type in a positive integer to specify the number of samples to import into the Series. Specify "ALL" if you want all the data points imported. The default value is "ALL".
