How do i skip several lines in an open TEXT file?

Hello.

I attached a picture of my text file, to emphasize:

Frame  Ty  Tx
============================
1  509.50  1141.50
2  509.50  1141.50
3  509.50  1139.50
4  511.50  1139.50

I need to skip the headlines and i need an easy way of reading the remaining lines of the file, i.e. the numbers.

for example i need an easy way of obtaining only the numbers :

1  509.50  1141.50
2  509.50  1141.50
3  509.50  1139.50
4  511.50  1139.50

And then to easily use each row and to obtain the data from the remaining file as obtaining numbers from a matrix(i.e skip the uneaven spaces between each coulmn :

C{1}:
1
2
3
4
C{2}:
509.50  
509.50  
509.50  
511.50
C{3}:
1141.50
1141.50
1139.50
1139.50

Thank you.

Open the .txt file using fopen:

fid1 = fopen('filename','r');

Then I suggest using textscan to read your data. You can use 'HeaderLines' to specify how many opening lines to skip:

data = textscan(fid1,'%f %f %f','HeaderLines',2)

This will read your data into a cell array. If you wish to access row,col indices, you can convert this to a matrix:

c = cell2mat(data);

Hey Anna, thank you for your answer, but i encounter a problem after i use the textscan function . the problem is showen in the attached picture. What should i do?

Your system must be set to hebrew and MATLAB uses this as its default encoding. Try this

fid1 = fopen('TargetLocation.txt', 'r', 'n', 'US-ASCII','HeaderLines',2); to open the file.

I tried but its too many input arguments for the fopen function. And then i used it like this :

and its fixed the problem but i still recieve a zero matrix in C. :P
