I need to import data from a .TXT file.
Skip header
Data in different variables (Ex: time, Ch1, Ch2 and Ch3)
I can't do it, does anyone have any examples?

opt = {'HeaderLines',20};
fmt = repmat('%f',1,4);
str = fileread('temp0.txt');
C = textscan(strrep(str,',','.'),fmt,opt{:});
time = C{1};
Ch1 = C{2};

Sorry to return in the post,
I have one more difficulty.
Some exported files have different settings.
Instead of having (,) has (.)
Can you convert to (,) on import?
Example:
