Wow! Thank you for taking the time to write great explanations! I have printed it out and will re-read everything to really understand it.
Instead of creating new threads, is it okay if I keep posting new questions in this thread?
If so, I have a question on creating variables. I have tried to research and come up with a solution (to the text quoted below) on my own but I do not know if I am on the right track. If possible could you tell me if I am moving in the right direction?

So as far as trying to distinguish between "100_eddy_corrected_brain.nii.gz" and "100_eddy_corrected_brain_mask.nii.gz" if you could define the first as a variable, say $eddy_file or something of the sort, you could pipe it through to a cut command defining a period as your delimiter and take everything in front of it, so something like:
{echo $eddy_file | cut -d. -f1}_mask.nii.gz
But that would depend on using the "set" command to create the variable.
I have come up with the following: though I am not sure what is meant by using the 'set' command.
The eddy_corrected_brain.txt is a text file with pathnames of all the files that match eddy_corrected_brain.nii.gz from the initial find command/results.

shell-quote
SHELL-QUOTE(1p) User Contributed Perl Documentation SHELL-QUOTE(1p)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
