comment A SetDelayed issue
If your thesis advisors come across this on a web search, they will merely see that you sought help from others to clarify an issue about Mathematica. Isn't that a normal part of writing a thesis?

comment ReadList importing negative times
Thanks for sending the file. It turns out that ReadList parses the input differently from what I had imagined. (see second attempt, above.)

The output in the first gray box is already transformed by Mathematica. Cutting and pasting it does not provide a list. I could try to guess how the data looked in the file form, but I prefer to review the actual file.

If you post a link to your data file, others may be able to help with the importing via ReadList.

comment ReadList importing negative times
Would you show the data as imported, before you manipulate it? I suspect that the number -0 is already read in as 0. If you read in "-0" as a string, you should be able to retain the minus sign.

comment Viewing Mathematica Demonstrations Project Code
Would you send a link to a particular demonstration, the code of which you have not been able to view? That way, we may see what you are experiencing. BTW, did you mouseover the places where the cell brackets normally appear. They may simply be hidden from view.

comment How to get rid of trailing string after using Convert?
Convert does not appear to be a built-in Mathematica function. Are you using a package where Convert is defined?

comment data visualization on a lattice grid
You have only drawn a single arm. To display an angle, one needs two arms and a symbol to show the sweep from one arm to the other.

comment PaddedForm adds an additional padding character
I believe that PaddedForm adds padding to the left/right regardless of what is in the middle

comment How can I find if the number of subsets for a list is very large?
Do you really need to obtain all of the subsets? Would a partial list suffice? E.g. subsets with at most n elements? Or subsets with between n and m elements? Or a "random" sampling of subsets?
