Matlab error when I try to load a file

Hi all,

I loading a file called:

A=load('epitime.txt')

and I always get this error message:

??? Error using ==> load
Unknown text on line number 1 of ASCII file
C:\Users\Liliane\Documents\MATLAB\stage
usa\temps_distance\epitime.txt
"ARU".

Error in ==> code_temps_distance_filtre4 at 5
A=load('epitime.txt');

Initially my file has the extension epitime.fil4 and I got the same message error so tried with epitime.txt,but I make no difference.

My file consist in columns like this :

ARU     2.2888  03:23:14 
      (distance)  (HH:MM:SS)

Could someone help me please ?

Thank you

Hi all,

I posted a message a few minutes ago about an message error I got:

My file consist in columns like this :

ARU 2.2888 03:23:14 (distance) (HH:MM:SS)

I got an answer that I should use textscan,so I did it :

clc
clear all
close all
%loading data
fileID = fopen('epitime.txt');
C = textscan(fileID, '%s %f %s %f')
fclose(fileID);
celldisp(C)
%epicentral distance in°
dis=C(:,2);
%time in HH:MM:SS
time=C(:,3);
%distance in kilometer
dis_km=dis*111.12

%time in Secondes

but the problem is now that I can't convert the time HH:MM:SS in my file to seconds and my distance in degrees can't be converted in kilometres,too. What should I do ?I don't know any more what to do..I'm completely lost :(

Thank you

See: textscan

If you were working by hand, how would you convert a distance "in degrees" to kilometers?

My speculation would be that you have several entries for the same earthquake, and you need to triangulate between the readings in order to convert the angle measurements into distances.

Answer 1

[Walter Roberson]

When you use load() of a .txt file, the file must be in save -ASCII format. In that format, text can only appear following comment markers. You will need to use a different routine to load files with the format you describe.

Thank you , Which routine should I need for loading the files?I don't know how to do that..:(

Answer 3

Sorry, I didn't see the link you put...I will see that ..Thank you

Answer 4

I have to convert the time HH:MM:SS to seconds and the distance in degree in kilometre.By doing that I can't any more convert my HH:MM:SS..Is there a method to do that with the cells?
