Devices' 200 John Collette FRAME,SUB FRAME,1V,2V,3V,4V,5V 1,1,.343,.234,.233,3.23,.233 2,1,.348,.254,.274,3.53,.243 &same amount of rows as 1st set ] I will be importing files in which, the amount of rows in the first set is not consistent. (so one file will have 300 rows, the next one 328,random amounts) How do I deal with the blank line that comes between the sets. Can I use it as a signifier that four lines of text are next?

Please post the format of the file formatting with the code button and seprating it from other text.

It's important to define the number of columns, so what happens to the line at ",... % so"?

foo = textscan(fid,'%f%f%f%f%f%f%f','Delimiter',',','Whitespace','','HeaderLines',4)

This will skip the 4 header lines and read 7 floats per line after that. It will stop reading when it gets to EOF or a blank line. At that point you can repeat the textscan() as-is to get the next group.
