how do i use textscan to display strings have spaces in between ?

Hi friends, i have used this code with textscan:

fidpw= fopen('yy.txt','rt');
format = repmat('%s ',[1 row1]);
Pat = textscan(fidpw,format );
fclose(fidpw);

i used texscan to display the columns in this file but it doesn't work well because of the space existed in between the first rows of its corresponding columns

the columns looks like :

col1={stage iiib;t3;n1;m0}

col2={stage iv;t4;n1;m1}

code output looks like:

col1={stage;stage;t3;n1;m0}

col2={iiib;iv;t4;n1;m1}

?????

is this because i used %s in textscan ???

Thanks in advance!

In that situation, you should

Pat = textscan(fidpw, format, 'whitespace', '', 'delimiter', ';');

Error using textscan
Buffer overflow (bufsize = 4095) while reading string from
file (row 1 u, field 1 u).  Use 'bufsize' option. See HELP TEXTSCAN.

iic  stage iia  stage i  stage iiic  stage i  stage iva  stage iia
stage iia  stage i  stage iii  stage ii  stage iv  stage iiic
stage iia  stage iv  stage iib  NA  stage iiib  stage iiib  stage
iii  stage iv  stage iii

Patient = textscan(fidpw,format, 'whitespace','','delimiter',';') ;

In that case I need an actual input file to look at.

@Walter Roberson, could you check the input file format?

[Walter Roberson]

ncol = 12;
fmt = repmat('%s', 1, ncol);
fid = fopen('Classeur1.txt', 'rt');
Pat = textscan(fid, fmt, 'Delimiter', '\t');
fclose(fid)

@ Walter Roberson Great bro!

Works Well. the key point is the delimiter '\t'

Appreciate your help! Always perfect answers from you .

[KSSV]

fid = fopen('my text file','r');
S = textscan(fid,'%s','delimiter','\n') ;
fclose(fid) ;
S = S{1} ;

Note that S will be a cell. You can access your required line using S{i} . Where i is your line number.
