MATLAB: I want to delete all the headerlines and delimiters from the data in the below attached text file

headers

Hello Everyone

I want to delete all the headerlines and delimiters from the data in the below attached text file to execute if-else statements on the data of 2nd and 3rd column of the text file . I am able to delete the headerlines and delimiters only from the first 41 cells of the data.

%% Open the text file 
fID = fopen('dil_stress_strain.txt','r');
%% Read columns of data according to the format.
stress=textscan(fID,'%n %n %n','headerlines',7,'Delimiter','');
%% Close the text file.
fclose(fID);

Please help!

The best solution is probably to read your entire file as text, then remove the header lines, then parse them with textscan.

You are closing the file in the loop. close the file after the loop. I assume the below should work.

function read_datapattern(filename)
fid = fopen(filename,'rt');
if fid < 0
  error('error opening file %s\n\n',filename);
end
pattern = fgets(fid);
for n = 1:32767
  nextline = fgets(fid);
  pattern = strcat(pattern, nextline);
fprintf(pattern);
fprintf('\n');
end
fclose(fid);

MATLAB: Import data from a .txt file with multiple delimiters and headerlines

dataCell = textscan( fid, '%*3c%s%s%f%f', 'Delimiter', ',', 'HeaderLines', 2 );

Then

sernums = datestr( strcat(DataCell(2), ' ', DataCell(1)) );
output = [sernums dataCell{3} dataCell{4}];

This would convert the times and dates together as serial date numbers. If you want the columns to be separate as you show in your example, then

sernums = [datestr( DataCell(2) ), datestr( DataCell(1) )];
output = [sernums dataCell{3} dataCell{4}];
