Data export

HPSpec saves recorded spectra in a proprietary format that cannot be read by other programs. A macro extension has been written that allows to save data as ACSII text file.

There are two ways of transporting (exporting – importing) data. First involves saving each spectrum one-by-one and importing them the same way. This is a more straight-forward way, but is substantially more laborious.

The better way is to assemble all spectra in a series into a matrix, i.e. a 2-dimensional array, and transporting as a single file. While this method will involve learning of matrix handling, it is faster and beneficial in the long run.

To make matrix from spectra follow recommendations here. Make sure your spectra are arranged in the known, logical order, perhaps in the order of sequential additions. You should be able to tell what exact conditions each spectrum was taken at by its order in the sequence. It is a good idea to include the first blank vs. blank spectrum as the first entry.

Select these spectra and use make matrix from spectra macro to convert data into a matrix form. Look for matrix that you created in the MATRICES folder; give it a name and a short description such as “Trp concentration titration”, for example. After you save matrix as a Chemstation file, select it again and export it as ASCII. You are now ready to import saved ACSII file into Igor.
