Now I am able to read the ascci file in matlab. I want to
convert characters to their ascii values. for this I am
using a loop to access the values from the original file
and using abs command to convert to the ascii value.
like
x=s(i,j)
abs(x)
but its not giving the value of the particular element.
rather it prints the values of s ( i j ).
can anyone help me?

Hi Prash
The file you have sent me looks like this.
I dint know how this symbols correspond to numbers.

Patient Id:1234

0:0:1:! fJeJdIdIfJeJdI eIfJeJdIdIdJbJeK
hJrN{SSzRnWjUeMaGcIeIdJeJeKeLeKdJeJdJeJeKeJfKeJfJfKfLfJeJeKfL
eJ fJ gJfLfK fJ gK
gK
hK
gK hK iK iK iJ iK kL kL
jK
jK
kL
lL
kK
jK kL jK iJ hJ
......

I can give you an example how i read my files.
The file look like this:

Batch rate_cox_activ002.rre

Instrument ID 021617

Sample p1 rate

Data Mode A

Smoothing None

Date Collected 6/11/2008

Time Collected 3:24:36

mm:ss.sss Value

00:00.000 0.0711

00:00.125 0.0722

00:00.250 0.0707

00:00.375 0.0715

00:00.500 0.0712

....

to read it into matlab I use this code:

fid=fopen('file.txt','r');
s = '';
while ~feof(fid)
line = fgetl(fid);
if isempty(line), break, end
s = strvcat(s,line);
end
ro=length(s(:,1));
rate_data=[str2num(s(9:end,1:2))*60+str2num(s(9:end,4:5))
+str2num(s(9:end,6:9)) str2num(s(9:end,10:end))];

hope it helps.
