DIAdem

This option can be used to read in data from DIAdem format data files. After selecting a DIAdem header file a list of all the available channels will be displayed so the required channels can be selected.

Version 11.0 of T/HIS supports the following DIAdem data file formats

REAL32
REAL48
REAL64
INT16
INT32
WORD8
WORD32
ASCII

The MSREAL32, TWOC12 and TWOC16 are not supported.

By default T/HIS will display the channel comments (header block 201) for each channel. This can be changed to the channel names (header block 200) using the popup menu if required.

When channels are read in this option is also used to create the labels for each curve.

As well as displaying either the channel comments or the channels names the list of channels can also be filtered if required .

The filter string can contain the following wildcards

* matches multiple characters
? matches a single character

Note: The filtering ignores case.

Normally one of the DIAdem data channels contains the x-axis (time) values. By default T/HIS assumes this is channel 1 but this can be changed using the button labelled ...

If none of the channels contain the x-axis values then a start value and an increment can be specified to generate curves with evenly spaced x-axis values.
