Good Afternoon,

I am working with Matlab and have been for the last 5 weeks or so. I have been using the command importdata('filename.txt') for the same sets of data during this time. To my surprise today with a new set of data the importdata command is now calling my 2 column matrix a 1 column matrix. Thus I am not able to graph one column vs the other. Does anybody have any idea what is going on here? The files have the same exact format with a space delimeter before the first column and in between the two columns. There are two heading lines with the same space delimeter at in column 1.

Thanks for your help in advance, I hope somebody is smarter than me on this one.
