    Hey David,
          Thanks for putting together this program (so quickly!). Can you please share the source code, so that others can work on the debugging and feature-adding? Which programming language is it in?
        Needed features:
        Saving the reorganized data into a CSV file (ie. a text file in which each row is in a different line and each data cell in a row is separated from the next by a comma, the comma representing the beginning of a new column), which can then be displayed in a table in a word-processor or spreadsheet program (or re-opened into your program). See:
    http://en.wikipedia.org/wiki/Comma-separated_values

    Grouping the ones and zeros (bits) into bytes, to decode a possible grey-scale or color image. Our earth computers use 8-bit bytes. See:
    http://en.wikipedia.org/wiki/Byte

    Note that a binary number (ie. a byte) may be read in two opposite possible orders, from left to right or right to left, making it uncertain which of two possible values is the correct one. See:
    http://en.wikipedia.org/wiki/Endian

          Mike

      Hi Mike,

      This sounded like something that could be useful so I knocked up a quick program to convert a string of 0 and 1's to an image of specified rows/columns. It can be downloaded from http://www.groundcontrol.co.uk/seti/binimage.zip

      Its prob a bit buggy so let me know how you get on.

      Dave

            Can anyone please tell me where to download a freeware program which can convert a list of data (numbers) into a table of whatever dimensions one chooses? Relative to SETI, it could be used, for example, to try to find a picture embedded in a radio transmission, by arranging ones and zeros into 2-dimensional grids of different possible pixel heights and pixel widths of an image. I've already wasted too much time looking for this, so if anyone can help, that would be great.
               Thanks, Mike
