Format of Input Spectra

• The input format of spectra is based on non-encrypted text files; no proprietary or encrypted formats can be used.
• The data may be arranged either in columns or in rows.
• The first column or row of data has to be arranged in a sequence of either increasing or decreasing values as it represents the X-axis (horizontal).
• Regardless of the format, the X-axis of the spectrum will always be depicted from low wavenumbers to the left, to high wavenumbers to the right.
• The following (2nd, 3rd, ...) column(s) or row(s) of numbers represent(s) one or more Y-axes (vertical), for single or multi-spectra files, respectively.
• The numbers in the input file can be separated by a tabulator (tab-delimited files), space, comma + space, or semicolon.
• A sequence of separators is interpreted as a single separator.
• The decimal point can be both in the form of a comma or a point.
• The maximum number of Y-axes (spectra in a multi-spectrum) is unlimited in theory, but in practical terms, it should be limited to a few hundred at most.
• The file as a whole can have an alphanumeric header, which is ignored in the current upload procedure.
• If a row or column is initiated with an alphanumeric string, this is ignored as well. However, we plan to introduce a function that allows using this string for naming the individual spectra in the multi-spectrum format. So far, if you upload a multi-spectrum, please mind that the individual spectra will be named only as Y1, Y2, Y3.... etc. If necessary, add a legend to the “note” section of the input form, such as Y1 = “my spectrum 1,” Y2 = “my spectrum 2,” etc.

We will update the info on the accepted and recommended input format as we continue to refine the approach.
