Read Data From txt file using uigetfile...

Hi

I Have to read a file using uigetfile by this code by i face the error...

[filename,pathname,d] = uigetfile('*.txt;');
filepath=fullfile('pathname','filename');
fid   = fopen('filepath');
mline1 = textscan(fid, '%f%s%s%f%f%s%s%f%f ','HeaderLines',5);
fclose(fid);

Error:

Error using textscan
Invalid file identifier.  Use fopen to generate a valid
file identifier.

By The Way I Already have done it without using uigetfile...

another point is data should be a number not a string cause they are going to plotted... What should i do to convert them???

For the bit about it needing to be a number, we need a sample input line.

do not put the aote matks around filepath.

fopen(filepath)

I Need To Use uigetfile... Actually

[Walter Roberson]

[filename,pathname,d] = uigetfile('*.txt;');
filepath=fullfile('pathname','filename');
fid   = fopen(filepath);     %no quotes around filepath

Dear Walter...

the error is for this line :

 mline1 = textscan(fid, '%f%s%s%f%f%s%s%f%f ','HeaderLines',5);

and the error's text is again the above one...

[Walter Roberson]

[filename,pathname,d] = uigetfile('*.txt;');
filepath=fullfile(pathname, filename);  %no quotes around pathname, filename
fid   = fopen(filepath);     %no quotes around filepath

thanks but the results is shown like:

[10x1 double]

i want them to be a real number cause they have to be added and plotted...

cell2mat(YourArray)

[Masoud Ghanbari]

cell2mat does not work when i have %f or %s in the textscan command... such a like this...

mline1_cell= textscan(fid, '%d %d %f %f %f %s %d %*[^\n] ','HeaderLines',5);
cell2mat(mline1)

>> error

????

[Walter Roberson]

mline_num = [mline1{[1:5 7]}];
mline_txt = mline1{6};

Thanks Dear Walter And Dear Azzi...
