Script to make simple recurring ascii file edit

Hi,

I have an ascii file with recurring lines (the file is 36mb so lots of lines) which look like this:

-2.5 -66.324-68.138 935.2 1.953 -0.664 272.617 73.684 -2.428 269.998 0.000

Every 14 lines there is a blank line.

I would like to, for each non-blank line, introduce a space at the 15th character space in the line (i.e. in the above between the '4' and the '-' so I separate the two numbers to give -66.324 -68.138 rather than -66.324-68.138). I want this applying to the first 13 lines, but not the 14th, the next 13 lines but not the 25th, and so on.

Is a short shell script best to sort this? Any help is much appreciated.

Thanks Andy

GIT-STRIPSPACE(1)						    Git Manual							 GIT-STRIPSPACE(1)

NAME
git-stripspace - Remove unnecessary whitespace SYNOPSIS
git stripspace [-s | --strip-comments] < input DESCRIPTION
Clean the input in the manner used by git for text such as commit messages, notes, tags and branch descriptions. With no arguments, this will: o remove trailing whitespace from all lines o collapse multiple consecutive empty lines into one empty line o remove empty lines from the beginning and end of the input o add a missing to the last line if necessary. In the case where the input consists entirely of whitespace characters, no output will be produced. NOTE: This is intended for cleaning metadata, prefer the --whitespace=fix mode of git-apply(1) for correcting whitespace of patches or files in the repository. OPTIONS
-s, --strip-comments Skip and remove all lines starting with #. EXAMPLES
Given the following noisy input with $ indicating the end of a line: |A brief introduction $ | $ |$ |A new paragraph$ |# with a commented-out line $ |explaining lots of stuff.$ |$ |# An old paragraph, also commented-out. $ | $ |The end.$ | $ Use git stripspace with no arguments to obtain: |A brief introduction$ |$ |A new paragraph$ |# with a commented-out line$ |explaining lots of stuff.$ |$ |# An old paragraph, also commented-out.$ |$ |The end.$ Use git stripspace --strip-comments to obtain: |A brief introduction$ |$ |A new paragraph$ |explaining lots of stuff.$ |$ |The end.$ GIT
