here is the code for getting the data into matrix:

fid = fopen('test.csv');
[data] = textscan(fid, ['%d %llu %llu %lf %lf %lf %s %s %s %s' '%*[^\n]'], 'delimiter', ',','CollectOutput',true);
fclose(fid);

its producing textscan Badly formed format string. As a newbee i am not able to find any solution. anyone help please??

[John BG]

you have a few longer than 15 digits fields that mislead IMTool.

After adding some Returns, with IMTool i got this;

Try tweaking a few fields:

After removing all the '9' but one on the left, and zeroing the 0000001 IMTool imports data correctly

here is the code for getting the data into matrix:

fid = fopen('test.csv'); [data] = textscan(fid, ['%d %llu %llu %lf %lf %lf %s %s %s %s' '%*[^\n]'], 'delimiter', ',','CollectOutput',true,'HeaderLines',1); fclose(fid);

it still shows same error..:(

[John BG]

the following does not crash

[data] = textscan(fid, ['%d %u %u %f %f %f %s %s %s %s %s %s'],'delimiter', ',','CollectOutput',true,'HeaderLines',1);

[Walter Roberson]

textscan does not permit the 'l' modifier. It uses numeric suffixes, such as %u32 . See http://www.mathworks.com/help/matlab/ref/textscan.html#inputarg_formatSpec
