Features of DNA Stacks HyperCard 2.0 stacks
Version 1.1 (12/95) Copyright 1990-1995 D. J. Eernisse

For a description of version 1.0 see:

Eernisse, D. J. 1992. DNA Translator and Aligner: HyperCard utilities
    to aid phylogenetic analysis of molecules. CABIOS 8: 177-184.

DNA Stacks is a software package of HyperCard 2.x stacks providing
complementary sets of utilities for viewing and manipulating molecular
data on a Macintosh computer.

The best way to get the most current version of DNA Stacks is from the
author's home page:
<http://biology.fullerton.edu/people/faculty/doug-eernisse>.

The stack package has three main stacks: DNA Translator, Aligner,
and Codon Usage. The package also includes a stack called Startup, which
is used internally by the other stacks, and File Combiner, which is a
more general utility stack useful for combining folders of sequence files
together.

DNA Translator stack has two kinds of "cards." A gene mapping facility draws
and displays 2 linearized gene maps for comparison, automatically
adjustable to desired scales and locations along all or part of the mapped
molecule. Maps and select corresponding complete sequence data are provided
for most available fully documented mitochondrial and chloroplast DNA
(mtDNA and cpDNA) sequences, which include 26 animal, 1 yeast, and 1 ciliate
mtDNAs and 3 green plant cpDNAs. Additional gene maps may be user-created
by a direct file conversion of standard GenBank- or EMBL-format documented
sequences and their features tables.  A user can extract the
sequence of any particular mapped gene or region by clicking on
the corresponding place on the gene map or by menu selection of the gene or
feature and mapped taxon.  DNA Translator utility cards are a
workbench of specialized sequence manipulation tools, catering especially
to those with interests in phylogenetic analysis. DNA Translator can also import
single or multiple sequences in a variety of formats, including multiple aligned
sequence output of various programs (EuGene, Prophet, CLUSTAL, Nexus,
PHYLIP, etc.), and then further manipulate, interleave, compare or
translate the gene sequences to amino acids. Multiple aligned sequences can
be converted to Nexus, Hennig86 or PHYLIP for subsequent phylogenetic
analysis. Most known deviations from the "universal" code, which are
typical for mtDNAs, may optionally be used during translation.

Note that extraction of animal mtDNA sequences and many of the
translation/report utilities are now available and easier to use from
the "Data" menu of Aligner stack, described next.

Aligner is a stack for manual editing and display of multiple sequence alignments.
Aligner 1) handles up to 100  sequences, each up to 30,000 bp or amino
acid residues in length; 2) displays sequences as "interleaves" with the number
of lines automatically adjusting for the number of sequences imported;
3) imports or exports multiple sequences by default in "named" string format
(i.e., 'Name<space(s)>AGCTGA...<rtn>'), which is the same as PAUP's "simple text"
format; 4) additionally will import/export numerous other formats that are widely
used, including support for interleaved sequences; 5) additionally will export a
wide variety of alignment/sequence reports or filtered sequence data;
6) can toggle between two window widths, either full 640 or 512 pixels
("standard" or "classic" monitor display widths) and can be expanded up to a
1200 pixel window length; 7) can quickly toggle between match characters
(dashes) to the first sequence and no match characters; 8) can more slowly
color-code base pairs, amino acids, or codons, including support of alternative
genetic codes; 9) supports addition/deletion of one or more gaps to all but the
current sequence; 10) speaks nucleotide/peptide characters during keyboard
entry or after entry starting from the current insertion point; 11) extracts
a selection of about 15 DNA or corresponding amino acid sequences to
Aligner, where the gene is any animal mtDNA gene and the sequences are a selection
of either metazoans or mostly vertebrate metazoan sequences; 12) allows one to align
amino acids, then introduce gaps to the corresponding unaligned nucleotide strings
to preserve the amino acid alignment; 13) has an error checking facility to check
current alignment against the starting strings, disregarding any added gaps;
14) has optional help facilities, including this general overview, a tutorial to
using Aligner, and a baloon-like help feature that optionally displays the function
of fields or buttons as the cursor enters them.

Codon Usage stack displays codon and amino acid usage data as it differs for a
wide variety of organisms and organelles. Dynamically-constructed graphs display
percentage usage for a particular codon relative to the other 63 codons or to only
other codons with equivalent amino acid coding. A user can select from a diverse
list of some 70 taxon-organelle combinations.

The codon usage, translation and gene mapping data can be exported or
imported in spreadsheet format for incorporating additional molecules of
interest or in various standard formats (UWGCG, GenBank,
EMBL,Intelligenetics). A built-in editor supports sequence entry with
optional computer-speaking for error checking, and a variety of output
conversion options.

New features added since version 1.0 (Eernisse, 1992)

General:

DNA Translator stack:
* gene mapping matrices can now be exported/imported from the menu of
  gene mapping cards, whereas before these features were hidden.
* Added a feature to report sequence composition statistics by codon
* modified interleave" format conversion so that first and last taxon
  names are guessed at before making the user enter them manually
* added support for Phylip input files and for the output created
  by GCG's "Pilepup" and Jotun Hein's alignment algoriths.
* multiple animal mtDNA gene sequences can now be exported to a single
  file or directly to Aligner, and amino acid sequences can be exported
  at the same time, in the case of coding DNA sequences
* added capabilities to test how likely it is that "signal" in a sequence
  alignment could be due to experimental error, rather than historical
  (phylogenetic) signal
* added a recoding option so that amino acid alignments can be treated
  as if it were DNA or RNA data (assuming equal weighting is used).
* it is now possible to create Nexus-format "Charsets" for use in PAUP
  from a comment line in a user's alignment
* it is now possible to extract only those sites in an alignment that
  were included in a charset to a second alignment file.
* one can now output matrices of pairwise transition/transversion tallies
  or pairwise percent identity for any number of named strings and,
  for the "Substitution" (transition/transversion) matrices, there is an
  option to specify whether the tallies should be reported by codon position
  for for all positions.
* added a feature for combining two alignments into a single alignment,
  provided at least one sequence is common to both alignments
* streamlined the GenBank/EMBL conversion so that a minimum of prompts are
  required from the user
* improved certain hierarchical menus in DNA Translator
* added facilities to create PAUP blocks to automate the calculation of
  "Support Index" values for all nodes of all input trees in Nexus format
* added the ability to calculate synonymous and nonsynonymous changes, using
  the method of Nei and Gojobori
* added a special purpose data conversion to make it possible to treat 2nd
  positions normal (A,C,G, or T) while ignoring transitions at all 1st and
  3rd positions
* added the ability to compute a log determinant distance matrix (see Mol. Biol.
  Evol. 7/94)
* added support for newer versions of HyperCard or HyperCard Player, but did not
  use any HyperTalk commands specific to the newer versions so the stacks should,
  in theory, work on all versions back to version 2.0

Aligner stack:
* added many options to color the alignments, including the ability to
  color triplets of DNA that corresponds to amino acid coding, or coloring
  according to chemical, functional, hydrophobic/hydrophilic, and ionic charge
  groups of amino acid sequences (or DNA triplets that code for amino acids.
* added an online tutorial that will give users practice working with
  some of the more advanced features of Aligner
* sequences with different genetic codes can be colored in a single alignmtent
* improved sequence selection, sequence entry, and key filtering for editing
  data in Aligner
* improved several of the navigation buttons and indicators
* the card size in Aligner is now adjustable so that if one has ample RAM,
  it is possible to draw even an entire lib
* improved handling of RAM shortages
* add n gaps to all but the currently selected sequence
* calculate a DNA alignment that is identical to the corresponding protein
  alignment
* added an error checking facility to check manually edited sequences against
  the starting strings, disregarding added gaps, etc.
* added a color editor facility so that the colors used for nucleotides or peptides
  can be specified by a user


New features added since version 1.0n6 (last version posted to indiana
    archives <ftp://ftp.bio.indiana.edu>, 8/94)

General:
* a new stack "Codon Usage" was created to split off what was formerly part
  of DNA Translator
* revised help facilities throughout
* added a more colorful "About DNA Stacks" dialog
* enhanced the appearance of the startup process
* new icons
* resources and scripts common to Aligner and DNA Translator were moved to a
  new "Startup" stack used by both of the other stacks
* the new "Startup" stack also helps with more reliable expansion of the card
  size in Aligner
* added support for newer versions of HyperCard or HyperCard Player, but did
  not use any HyperTalk commands specific to the newer versions so the stacks
  should, in theory, work on all versions back to version 2.0


DNA Translator stack gene mapping cards:
* reorganized menus on gene mapping cards, with some options now available
  from a new "Extract" menu
* import/export features were enhanced for gene maps
* gene map selection lists now also include common names as well as scientific
  names, and these are listed in approximately phylogenetic, rather than
  alphabetic, order
* more than 25 animal mtDNA maps are now available, and these have been split
  into a "Metazoan mtDNA" card and a "Vertebrate mtDNA" card

DNA Translator stack utility cards:
* these are still used but mostly without the user ever knowing it, because
  most conversion/report options that were formerly only available from utility
  cards are now more directly accessible from the "Data" menu of Aligner
* added a "Multistate -> Binary" conversion
* added a feature to find all repeated sequences of n length in a large
  genomic sequence, with an option to decrement n until such repeats are
  found

Aligner stack
* completely reorganized menus so that all file opening, saving, and
  manipulations of data in the editor can be performed using the "Data" menu.
* most of the data format conversions or reports that were formerly possible
  only from utility cards in DNA Translator are now available from the simpler
  menu structure of Aligner
* added support for Phylip input files
* it is now possible to use Aligner's menu to extract multiple animal mtDNA
  sequences for any specified gene regions directly to Aligner, whereas it was
  formerly necessary to extract them from the gene mapping facility of DNA
  Translator
* Aligner now automatically detects the proper genetic code if the sequences
  were extracted from the gene mapping facility
* improved export of Nexus (PAUP/MacClade) format from within Aligner stack,
  including automatic provisions to interleave, match, and set data type
  appropriately
