| Data should only be submitted in simple ASCII
XY format as a last resort when no other formats will work. In almost all cases, your
instrument software will support export to one of the generic or other instrument formats
supported on this site. When a spectrum data file in ASCII XY format is submitted, the
following rules must be observed or else the file will not be recognized by the
SmartConvert software:
| 1. |
The data in the file must only consist of alternating pairs
of X and Y values (X value first) separated by spaces, commas, tabs, or carriage returns.
The best format for the data is with one XY pair per line as follows:
|
|
| 4000 |
0.951 |
| 3998 |
0.942 |
| 3996 |
0.948 |
| etc. |
|
|
|
|
| 2. |
The very first character in the first line of the file must
be either a tab, a space, or a number. |
|
|
| The ASCII XY translator reads data from the
submitted file by assuming that all data point values it finds are alternating X & Y
values. The smallest X value found is assumed to correspond to the first Y value and the
highest X value to the last Y value regardless of the order of the X values in the file.
In addition, only the highest and lowest X values are used and the data points are assumed
to be linearly spaced throughout the X axis range. |
|
| Since there is no way to determine if the Y
values are in Absorbance or Transmission, or if the X axis is for FTIR (Wavenumber) or
Raman (Raman Shift), you will have to assign the spectrum type and Y axis units in the
data preview step before continuing with your search. |
