I am stumped with a few poorly scanned two column pdf which k2pdfopt "can not" reformat to a single column. I have used erase vertical lines option and cs option. I would be obliged if you could help me with this. I attach one of the problem pdf.

@Khin99 -- Thank you for the attachment. Because the scan is poor quality and the position of the pages changes a fair amount from page to page, a brute force cropping or gridding is best, I think. If you don't care about chopping up the title page, you can just do this:
k2pdfopt -grid 2x1x0 -mode fitpage source.pdf
-grid 2x1x0 breaks each page into 2 x 1 boxes.
-mode fitpage puts each of the gridded regions onto a single page
In the MS Windows GUI, you can just select "fitpage" for the conversion mode and put
-grid 2x1x0 in the "Additional Options" box.
If you want to preserve the title page, it's a little trickier, but not too bad:
k2pdfopt -cbox1 0,0 -cbox2- 0,0,.5s,1s -cbox2- 0.5s,0s -mode fitpage source.pdf
-cbox1 0,0 creates a boxed region on page 1, upper left corner at 0,0 and (by default), extending the full size of the page.
-cbox2- 0,0,.5s,1s creates a boxed region on pages 2 and up, upper left corner at 0,0, with width 0.5 x the source page (0.5s) and height 1.0 x the source page (1s).
-cbox2- 0.5s,0s creates another boxed region on pages 2 and up, upper left corner starting half way (0.5s) across the source page and at the top (0s), and extending to the remainder of the source page (by default).
