fid=fopen('RainFallReport9.txt')
s=textscan(fid,'%s','delimiter','\n')
fclose(fid)
s=s{:}
idx=find(~cellfun(@isempty,regexpi(s,'additional information')))
b=s(idx:end)

Sir, again kindly help.

[Azzi Abdelmalek]

fid=fopen('RainFallReport9.txt')
s=textscan(fid,'%s','delimiter','\n');
fclose(fid);
s=s{:};
idx=find(~cellfun(@isempty,regexpi(s,'additional information')));
b=s(idx:end);
idx=find(~cellfun(@isempty,regexp(b,'xy','match')));
a=regexp(b(idx+1:end-1),'[\.\d]+','match');
data1=str2double(reshape([a{:}],[],2));
c=b(3:7);
d=regexp(c,'\d+(?=\d)','match');
data2=str2double([d{:}])';
data1
data2

[Kanakaiah Jakkula]

I still not getting the xy data as I want I am getting the data1 as below: data1 =

     14.0000    0.2200
      0.2800         0
     13.0000    0.2300
      0.2700    1.0000
     12.0000    0.2200
      0.2600    2.0000
     11.0000    0.2200
      0.2500    3.0000
     10.0000    0.2200
      0.2400    4.0000
      9.0000    0.2200
      0.2300    5.0000
      8.0000    0.2200
      0.2300    6.0000
      7.0000    0.2200
      0.2200    7.0000
      6.0000    0.2300
      0.2200    8.0000
      5.0000    0.2300
      0.2200    9.0000
      4.0000    0.2300
      0.2200   10.0000
      3.0000    0.2400
      0.2200   11.0000
      2.0000    0.2600
      0.2200   12.0000
      1.0000    0.2900

But I want is as below:

-14  0.28
-13  0.27
-12  0.26
-11  0.25
-10  0.24
-9  0.23

7  0.23
8  0.23
9  0.23
10  0.24
11  0.26

Because I want to plot column1 vs column2 later.

Sir, sorry to bother you, please help me. Sincerely, Mekala

Change this line

a=regexp(b(idx+1:end-1),'[\.-\d]+','match')

[Kanakaiah Jakkula]

I still get the answer as below:

-14  0.22
0.28  0
-13  0.23
0.27  1
-12  0.22
0.26  2
-11  0.22
0.25  3
-10  0.22
0.24  4
-9  0.22
0.23  5
-8  0.22
0.23  6
-7  0.22
0.22  7
-6  0.23
0.22  8
-5  0.23
0.22  9
-4  0.23
0.22  10
-3  0.24
0.22  11
-2  0.26
0.22  12
-1  0.29

But I really want as below:

-14  0.28
-13  0.27
-12  0.26
-11  0.25
-10  0.24
-9  0.23

-7  0.22
-6  0.22
-5  0.22
-4  0.22
-3  0.22

-1  0.22
0  0.23
1  0.22
2  0.22
3  0.22
4  0.22
5  0.22
6  0.22
7  0.23

data2

[Kanakaiah Jakkula]

Sir,
Thank you very much, but lastly I want to ask you about:
c=b(3:7);
Acually the below one is not a fixed one, but it will vary:
1. Alarmtype1 heater volt:1670890
2. system error:5480
3. Alaram, voltage, event ID:46754
4. warning, id:15643
5. warning current, event id:76542
I mean 1~5 will vary, may be some time 1~3, some time 1~4, or some time 1~8 or what ever. That is why instead I want to stop when dotted line appears (--------) for this Data2 storing. 

One more thing, I have to read multiple text files from the directory at the same time. I attached herewith four text files for example.

May I humbly request you to kinldy help,
Sincerely, 
Your's

[Kanakaiah Jakkula]

Sir,

I want to read multiple files, please help me which part of the code should be changed. Sincerely, Mekala
