Hi,
Once you get SR1 going, just drag-and-drop the SPC file onto the gray area of the Origin interface (outside of any window). This will then create a new worksheet with just one Y column with the SPC data in it. You can then right away do the menu command "View->Show X Column" to create your X column.

Hello,
What version of Origin do you have?
I think the problem you are experiencing was a bug in the 7 release version, and has been fixed in the SR1 patch.

thanks for your suggestions. I did as you described, but it still didn't work.I paste the information of the spc file as below:
EvenX Initial Value:397.335144042969
EvenX Increment:1.9288112809433
header info:
[MainHeader]
FileName = D:\data\IR\VAPOR.SPC
Instrument technique code = 0
Number of points in the file (if not XYXY) = 2077
Floating X coordinate of first point = 397.335144042969
Floating X coordinate of last point = 4401.54736328125
Integer number of subfiles (1 if not TMULTI) = 1
Type of X axis units = 1
Type of Y axis units = 2
Type of Z axis units = 1
Date/Time = 07/19/1994 19:50:00:000
Resolution = 4. cm-1
Source instrument =
Peak point number for interferograms (0=not known) = 0
spare =
comment =
X axis label = Wavenumber (cm-1)
Y axis label = Absorbance
Z axis label = Arbitrary
File Modification Flags =
Method/program/data filename =
Z subfile increment = 1
Number of planes for 4D with W dimension (0=normal) = 0
W plane increment =
Type of W axis units =
[SubHeader]
Subfile Index = 1
Located column Name = B
Subfile's starting Z value = 1
Subfile's ending Z value = 1
Number of subfile points for TXYXYS type =
number of co-added scans or 0 (for collect) = 1
Waxis value =
[Log Text]
i wish to see the service package of the bug soon, thanks! |

Hi,
I suspect your SPC file is such that the EvenX Initial Value and EvenX Increment are both 1. You can check this by double-clicking on the black triangle. For SPC files of this type, there is a bug - the View->Show X menu item is not available if the Y column with the SPC data is the very first column in your worksheet.
This bug may get resolved in the next service release. For now, try this workaround:
1> Open a new worksheet
2> Change the A col to type Y and fill in some number in the first row
3> Drag-and-drop your SPC file onto the worksheet - Col B will have your SPC data
4> Highlight Col B and use the menu command View->Show X Column. This will add an X column (named col C) to the left of B, and that will have the X information.
5> Delete col A.
You can now save the project and reopen in 6.1.
For SPC files that have x increments not equal to 1, this problem does not exist.

Hi,
Origin 7 stores the X information from SPC files in the column, and uses the information when creating a plot, for instance. In 7, the X information can be viewed by double-clicking on the black triangle in the header of the Y column to bring up a dialog that displays all the information that was available in the SPC file. Earlier versions cannot read this information.
If you select the Y column with the SPC data and then use the menu item "View->Show X Column", an X column will be added to the left of the Y column. You can then save the project and reopen it for use in ver 6.1
