*** Outline of the second method using one file via NoteTabLight ***

  • (A) Generation of JCAMP-DX file from topSpin2.1 operating system
  • (B) Modification of JCAMP-DX file via NoteTabLight and vice versa
  • (C) Introduction of JCAMP-DX file into topSpin2.1 operating system

(A) Generation of JCAMP-DX file from topSpin2.1 operating system

  • Consider the 29Si echo train file of nanomacs, already modified by convdta command:

  • File > Save; check "Save data set in a JCAMP-DX file"

  • Click OK button

  • Save the file on the DeskTop of Windows by filling the specify destination form:

  • A file called 29Si-nanom-4BL.dx appears on the DeskTop of Windows.

    This file is a text file containing NMR parameters and the intensities of the echotrain. The real part of this echotrain followed by the imaginary part are two ASCII series in a single column. The left-hand side of this column contains increasing integer numbers indicating the positions of the intensities. The right-hand side of this column contains the intensities of the echotrain.

(B) Modification of JCAMP-DX file via NoteTabLight

  • We use MS EXCEL to select the right-hand side of the column containing the intensities of the echotrain. To this end, we apply to the 29Si-nanom-4BL.dx file the procedure for converting two-series ASCII file into two-column (separated by tab character) MS Excel spread sheet document via NoteTabLight.

  • **************************************************

  • Now, we select the real part and the imaginary part of the echotrain and paste them to Java applet for denoising.

  • After the echotrain denoising, we replace the real part and the imaginary part of the echotrain in 29Si-nanom-4BL.dx file by the denoised values which are real numbers.

  • We change the format of these cells so that the intensities of the echotrain become integer numbers.

  • The intensities of the echotrain are integer numbers.

  • **************************************************

  • We again use MS EXCEL to merge the two columns into a single column. To this end, we apply to the 29Si-nanom-4BL.dx file in PRN format the procedure for converting two-column (separated by tab character) MS Excel spread sheet document into two-series ASCII file.

(C) Introduction of JCAMP-DX file into topSpin2.1 operating system

  • In TopSpin2.1, File > Open

  • Check "Open NMR data stored in special formats"

  • Click OK button

  • Click Browse button. Select copy-29Si-nanom-4BL.dx from the DeskTop of Windows then click Convert from JDX button

  • Click OK button

  • Denoised copy-29Si-nanom-4BL file is ready for processing in TopSpin2.1
