Before investing any time on a fix, I believe the original poster should specify what they mean by a single @. Is singularity determined by the immediately surrounding characters or by the contents of a field? For example, does a field such as ...|@\@|... consist of two singles, both of which should be replaced? Or should that field be left as it is? Similarly, in ...|@\@@|..., should the first @ be replaced or not?

You have given two contradictory explanations. It's probably best to start from the beginning, with a few lines of sample input containing as many distinct variations in field values as possible, along with the desired output.
This is probably not a complicated problem to solve, but not knowing exactly what should be done will likely result in wasted time on both sides, with us having to refine or scrap a first round of solutions, and with you having to ask for further assistance.
