Hi all! Thanks a lot for the prompt reply, specially to Mr.Hans Hagen and Mr.Tobias Burnus. I don't know anything about Ruby, so I tried using texutil - -epstopdf, but when the ghostscript window comes up it is blank and nothing happens after that. What do I need to do? I am attaching the commands that I gave to generate the pdf files .(See attached file: epstopdf.txt) Thanks in advance! Regards, -priya.
