MATLAB: I am looking to extract data from the following .dat file, where the actual data starts from line 14. If anyone knows the code to extract data from this format please let me know!

extract data from .dat file

filename= 'mydata.dat'; %this is your full filename

delimiterIn='\t'; %this is the delimiter, not sure if this correct

headerlinesIn=13; %this is where the header lines, data starts on line 14.

iload=importdata(filename,delimiterIn,headerlinesin)

This may work.

you could use textscan function:

fid = fopen('hextest.txt');

data = textscan(fid, '%s')

str='123456-123456.123.abcde';
num=regexp(str,'-[^\.]*','match');
num=str2double(num{1}(2:end))

Update

a=dir('*.bin');
b={a.name};
c=regexp(b,'-[^\.]*','match');
d=-cellfun(@str2double,c)
d =
      200000      200001      200002
