Hmm, that didn't work in my test. Passing more than one character to -F just returned the entire line as argument $1.

Code:
awk -F"\$%" '{print $1}' file

abc$%sdfhs$%sdf$%sdfaf$%
abc$%sdfhs$%sdf$%sdfaf$%
abc$%sdfhs$%sdf$%sdfaf$%
abc$%sdfhs$%sdf$%sdfaf$%
abc$%sdfhs$%sdf$%sdfaf$%
abc$%sdfhs$%sdf$%sdfaf$%
abc$%sdfhs$%sdf$%sdfaf$%

You could use sed to change it:

Code:
sed -e "s/\$%/:/g" file | cut -f3 -d:

sdf
sdf
sdf
sdf
sdf
sdf

Or use tr as noted earlier:

Code:
cat files | tr -s "$%" ":" | cut -f3 -d:

sdf
sdf
sdf
sdf
sdf
sdf

It appears the $% is causing issues with the -F command. If I replace the $% with ", ", I can run

Code:
awk -F", " '{print $2}' files2

sdfhs
sdfhs
sdfhs
sdfhs
sdfhs
sdfhs

And it works. I also tried the $% delimiter in an awk script and it didn't work either. I tried escaping one and both characters without success.

obconformer

obconformer(1)						      User's Reference Manual						    obconformer(1)

NAME

     obconformer -- generate conformer coordinates

SYNOPSIS

     obconformer # of conformers # of optimization steps filename

DESCRIPTION

     The obconformer tool can be used as part of a conformational study by generating random conformers using a Monte Carlo search. The best con-
     former out of the batch of conformers will be output, after taking the supplied number of geometry optimization steps. By default, obcon-
     former uses the MMFF94 force field.

EXAMPLES

	   obconformer 250 100 baseconformer.sdf >rotamer1.sdf

     Generate the best conformer (out of 250) of baseconformer.sdf and write it to rotamer1.sdf after 100 geometry optimization steps
