how to plot two-column text file of the energy spectra

Dear all,

as attached is a two-column text file of the energy spectra. anyone can help me to plot it?

[dpb]

Not a lot can do easily here w/ zip file; attach the text file itself -- just enough to see the format if it's other than just numbers.

What have you tried; where did you have a problem, specifically?

[mohd akmal masud]

sorry sir, this this file attached.

[Star Strider]

At least one is a binary file. What is the format? What are we supposed to do with it?

Uzip1 = unzip('point1.zip')

Uzip1 = 1×1 cell array
    {'point1.bis'}

Uzip2 = unzip('point.zip')

Uzip2 = 1×6 cell array
    {'point/point1.bim'}    {'point/point1.bis'}    {'point/point1.him'}    {'point/point1.int'}    {'point/point1.prn'}    {'point/point1.res'}

Uzip3 = unzip('point1 (2).zip')

Uzip3 = 1×1 cell array
    {'point1.bim'}

type(Uzip1{1})

Actually this is the instruction:

The output from the program is now in the files point1.res, point1.bis, and point1.bim. Print out point1.res and identify the different results from the description in the on-line manual. To get a readable version of the spectra, perform the command

bis point1

which now produces a new file point1.prn. This is a two-column text file of the energy spectra which can be imported to Excel or plotted using, e.g. the freeware gnuplot program. The file point1.bim is a floating point 64×64 matrix that can be briefly viewed by the command

bim point1

To convert to an integer image for display using, e.g. the ImageJ program, give the command bim point1/oi/nm:1000

A new point1 file with the extension *.int is now created and the maximum pixel value is normalized to 1000. You can now display this image in a display program

So all the file I was generate as attached here

Doesn't look too interesting, what's the data itself look like????

spec

spec = 17×2

NaN NaN NaN 1 NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN 32

Almost everything in what supposed to be a text file of numbers wasn't able to be read as numbers...what's the content of the file itself....?

Well, that's a text file, indeed, but whatever you did before zipping up the results did NOT result in the results described as "which now produces a new file point1.prn. This is a two-column text file of the energy spectra...".

You'll need to go through the steps as described; eventually somehow you'll manage to get a text file that does actually contain the data itself I presume, but it's simply too inconvenient of a form here to keep poking at when don't have a klew what all the stuff referred to is or where it came from or...

As the above shows, when you get to that desired .prn file, it will take almost nothing to read and plot it, but getting to that point is NOT a MATLAB problem; that's all tied up in whatever system it is that produced the data files and its toolset.

ADDENDUM:

Maybe the data follow the header??? This platform limits the amount of output shown so have to work around that to see anything -- that's why it so inconvenient to not have the text file itself attached...anyways, let's try

spec=readlines('point/point1.prn');  % read as text
whos spec

  Name       Size            Bytes  Class     Attributes

  spec      19x1              2374  string              

spec(19)

ans = ""

Well, that's not it, either -- readmatrix did the best it could; all that file contains is the descriptive data and the empty last record...

Dear @dpb and @Star Strider,

The raw file as attached is .prn (as attached)

Then I import data in excel (as attached)

Then I plot the graph using excel (as attached)

So now,i want to plot it using Matlab.

Can help me?

Answer 2

[dpb]

data=readmatrix('point1.prn.xlsx');
whos data

  Name        Size            Bytes  Class     Attributes

  data      512x2              8192  double              

plot(data(:,1),data(:,2))

Seems easy enough...

[mohd akmal masud]

yess....tq so much @dpb @Star Strider
