hyperbolic function in awk

Since:

sinh(x)=[exp(x)-exp(-x)]/2
cosh(x)=[exp(x)+exp(-x)]/2
tanh(x)=sinh(x)/cosh(x)

Therefore:

/usr/bin/awk '{print (exp($1)-exp(-$1))/2}' in.dat
/usr/bin/awk '{print (exp($1)+exp(-$1))/2}' in.dat
/usr/bin/awk '{print (exp($1)-exp(-$1))/(exp($1)+exp(-$1))}' in.dat

will give sinh, cosh, and tanh for the data inside in.dat.

An example is below, the first column is input, the rest 3 columns are output of sinh, cosh, and tanh using the above awk commands.

Multiple pages in one postscript file

The following is one postscript file with 3 pages. (I don't know why page 4 doesn't show up).
And the file doesn't always give expected result.

Looking for a research and/or service position in the field of NMR spectroscopy

I am looking for a research and/or service position in the field of NMR spectroscopy.

Generate publishable quality NMR spectrum by modifying Sparky plot ps file (3)

When postscript looks fine, open it in gimp
in the Load PostScript pop-window, Resolution 100-> 1000,
Width x10, Height x10, eg 826->8260, 1170->11700 then Ok,

It takes time to open, when finish loading, one can Crop image to get rid
of blank region, Scale image to the required size and resolution and save as tif or eps.

One can save a low resolution jpg version by modifying Scale image parameter or select a low Quality number(0-100) in the popup window after trying Save As a new.jpg

Generate publishable quality NMR spectrum by modifying Sparky plot ps file (2)

7, Change peak contour color
"/levelcolor n def" where n could be 0(black), 1(white), 2(gray), 3(red), 4(green) 5(blue), 6(yellow), 7(magenta) 8(cyan) etc.

8, To combine two or more postscript files, simply comment the showpage line and add showpage at the end of the very last postscript file. The relative positions, sizes can be adjusted by modifying some numbers in the combined postscript file.

9, "pt" command from Sparky generate postscript file of the spectra. In order to overlap two or more sets data, ppm/cm should be identical also "rt" make sure all sets with the same ppm range.

10, Useful postscript language like
0.5 0.5 scale (change size)
-200 400 translate (translocation, change position)

0.5 setlinewidth
254 400 moveto 350 400 lineto stroke (draw lines)

11, to write label A, B, ... or any other annotations
gsave
/Helvetica findfont 24 scalefont setfont
-238 685 moveto (A) show
130 685 moveto (B) show
-238 455 moveto (new annotations) show
grestore

Use "gsave ...... grestore" often (make life easier)

Generate publishable quality NMR spectrum by modifying Sparky plot ps file (1)

It is easier to use "vi" in a linux terminal to do the modification.

1, locate setlinewidth, change "1.0 setlinewidth" to "2.0 setlinewidth"
2, If there is label on the figure, change /LabelFont from /Courier to /Helvetica.
3, Label size can be optimized by changing the currentfont value near the end of the file.
4, Label can be moved simply by changing the number associated with the label in the ps file.
5, Axes can be hided by switching true to false near the beginning of the ps file
6, Two postscript files can overlap with different color or be arranged side by side.

music

Music is my hobby. I like listening to music. I like some old popular songs in Chinese, which is my native language. Some songs are just unforgettable. To someone like me, mp3 could be one of the best stuff around nowadays.

(note: mp3 is a music file format. Music from a CD can be converted to mp3 format easily using popular music player. And then you can listen to your favorite music simply by opening the mp3 file on your computer's music player software or any mp3 player, again and again and again ... How nice is that? Can one imagine that 20 years ago?)
