<p>I cannot say if the following is the best way to proceed, but when the number of columns differs, I always have a look to such functions in order to get the data: mopen/mgetl/grep/strindex and so on ... it need a bit of work.</p>
<p>The previous method work when the file size is not huge because mgetl loads in memory all the file first - in case of huge files (I mean with millions of lines), I need to adopt another strategy (bash file using awk - grep - seb and so on tool) in order to have a text/matrix file in a right format ... nevertheless I do not get strings so the previous method may not work.</p>
