Loading/read problems with tsv files in Matlab
Raady
I am trying to load files with file extension .tsv
I used a activex control in my guide, and added a functionality for double click using a command "uigetfile" to browse the file.
I could retrive filename, pathname, filterindex through this command.
I am stuck up with loading the file to do my manuplations, any suggestion would be helpful.
My tsv file contains like 30 columns and huge number of rows,
example
mon tue wed thu ...
100 200 300 400..
...
I need to read the first line of the matrix in text.
I tried to use with textread function , but i get errors.
Any suggestions with matlab or gui would be helpful.

What is the delimiter in your file?
And which error do you get?
You can try to use textscan to read the text files.
fid = fopen('Your_file.tsv');
C = textscan(fid, 'format');
in your case, format is going to be "%s";

Have you tried dlmread with a tab as the delimiter?

But dlmread docs say specifically that dlmread won't read files
containing non-numeric data like the OP has in the header.
OP needs to use textscan.
Read the first row with a sequence of %s (one for each column), then
read the rest of the file with %f (one for each column).
header=textscan(fid,repmat('%s',1,ncol),1,'delimiter','\t');
data=testscan(fid,repmat('%f',1,ncol),'delimiter','\t');
