============ CladeCompare ============ Compare protein sequence alignments. Identify diagnostic residues between the given "foreground" (FG) and "background" (BG) clades. If you use this software in a publication, please cite our paper that describes it: Talevich, E. & Kannan, N. (2013) Structural and evolutionary adaptation of rhoptry kinases and pseudokinases, a family of coccidian virulence factors. *BMC Evolutionary Biology* 13:117 doi:10.1186/1471-2148-13-117 Available at: http://www.biomedcentral.com/1471-2148/13/117 Freely distributed under the permissive BSD 2-clause license (see LICENSE). Installation ------------ A proper installation looks like:: python setup.py install If you have setuptools installed, the dependencies on Biopython_, BioFrills_, SciPy_ and ReportLab_ will be fetched and installed automatically. .. _Biopython: http://biopython.org/wiki/Download .. _biofrills: https://github.com/etal/biofrills .. _SciPy: http://scipy.org/ .. _ReportLab: http://pypi.python.org/pypi/reportlab Optionally, CladeCompare can align your sequences for you if you have MUSCLE_, HMMer3_ or MAPGAPS_ installed. .. _MUSCLE: http://www.drive5.com/muscle/ .. _HMMer3: http://hmmer.janelia.org/ .. _MAPGAPS: http://mapgaps.igs.umaryland.edu/ If you have the dependencies installed, you can use this package in-place, without installing it. Just download the source code (git clone, or download the ZIP file and unpack it) and include the top-level directory in your system path, or add symbolic links to cladecompare.py, cladereport.py and cladeweb.py to an existing directory that's in your path (e.g. ``~/bin``). Testing ~~~~~~~ Finally, if you are on a Unix-like system (i.e. Linux, Mac or Cygwin), you can verify your installation by running the test suite. Change to the ``test/`` directory and run ``make``:: cd test make If CladeCompare is installed correctly, the program will run in several modes and generate output files. View the ``.html`` files in your web browser to see what happened. Usage ----- Web interface ~~~~~~~~~~~~~ Launch the script ``cladeweb.py`` and fill in the form in your web browser. The form accepts sequences in FASTA or CMA format, and you can upload an HMM profile to align unaligned FASTA sequence sets. (See below for details about each field.) If you launched the application from the command line, press Ctrl-C (on Unix-like systems) to stop the web server application. Note that only one instance of the server will run on your system at a time; if you launch ``cladeweb.py`` twice in a row, another browser tab or window will open but the server will not restart. Command line ~~~~~~~~~~~~ The command-line interface ``cladecompare.py`` provides the same functionality as the web interface, plus a few more options. To read the built-in help and option descriptions:: cladecompare.py --help Two alignments are compared by specifying the foreground and background sets, in that order, as arguments:: # Compare two alignments cladecompare.py fg_aln.seq bg_aln.seq The program prints the following information for each column in the alignment(s): - The consensus amino acid types of the foreground and background - p-value indicating the significance of the contrast in amino acid frequencies - a little ASCII bar chart indicating contrast, based on the p-value. P-values are adjusted for number of columns in the alignment with the Benjamini-Hochberg "step-up" multiple-testing correction (false discovery rate, FDR). Redirect the output to a file with the extension ".out":: # Compare two alignments cladecompare.py fg_aln.seq bg_aln.seq > fg-v-bg.out Or specify the output file name with the ``-o`` option (same effect):: cladecompare.py fg_aln.seq bg_aln.seq -o fg-v-bg.out If you're not using MAPGAPS_, it would make sense to either: - Create a sequence alignment of all sequences, foreground and background, together; then divide the alignment into two FASTA files (e.g. by sequence ID). - Align both the foreground and background sets with hmmalign (HMMer3_) using the same profile, then use a script (your own) to delete any insert columns. In case you botch all that, CladeCompare will check then number of columns in the FG and BG alignments, and if they don't match, will automatically run MUSCLE to align the alignments to each other. To align the FASTA sequences with MAPGAPS on the fly, specify the profile name (minus the extension) with the ``--mapgaps`` flag:: # Align sequence sets w/ MAPGAPS, then compare cladecompare.py test/scttlre-domain.fasta test/cdc2-domain.fasta --mapgaps test/CDK_CMGC \ -o scttlre-v-cdc2.out Pre-aligned sequences in CMA format (.cma) are also accepted:: # Use pre-aligned sequence sets (MAPGAPS "CMA" format) cladecompare.py test/scttlre-domain.fasta_aln.cma test/cdc2-domain.fasta_aln.cma \ -o scttlre-v-cdc2.out Finally, given the '-p' option, cladecompare.py will write a "pattern" file listing the alignment column numbers with significant contrasts, in decreasing order (this can be useful input to other scripts of your own), as well as PDF files of paired sequence logos representing the foreground and background alignments around each significant site:: # Specify where the outputs go cladecompare.py fg_aln.seq bg_aln.seq -o fg-v-bg.out -p fg-v-bg.pttrn Outputs ``````` The script ``cladereport.py`` converts the "\*.out" files to an HTML file showing the alignment of the FG and BG consensus sequences, with the FG sequence colorized to show per-site contrasts (red=significant difference, blue=non-significant/columns are similar), inserts (yellow) and deletions (gray gaps):: # Visualize the per-site contrasts as a colorized alignment cladereport.py scttlre-v-cdc2.out > scttlre-v-cdc2.html Single- and multi-profile modes ``````````````````````````````` If a single sequence set is given, the aligned columns are compared to the overall amino-acid frequencies of the alignment:: cladecompare.py subfam1.seq -o subfam1-single.out When more than 2 sequence sets are given, each set is individually treated as a foreground and the rest treated as the background for evaluation:: # Compare several related alignments, e.g. all subfamilies cladecompare.py subfam1.seq subfam2.seq subfam3.seq ... This multi-mode generates and names the "\*.out" files according to the corresponding sequence file names. You can visualize these all together:: # Visualize each subfamily's contrasts together cladereport.py subfam2.out subfam2.out subfam3.out ... > somefamily.html Strategies ---------- Statistical tests ("-s" options) for column comparison: :gtest: (default) G-test for goodness-of-fit of FG amino acid counts vs. those of the BG column. BG frequencies include pseudocounts calculated from the amino acid frequencies of the full sequence set. :urn: Ball-in-urn model (binomial), a la CHAIN_, for counts of the "consensus" amino acid type in FG and BG. :jsd: Jensen-Shannon divergence of column compositions, a la INTREPID_. .. _CHAIN: http://chain.igs.umaryland.edu/ .. _INTREPID: http://bioinformatics.oxfordjournals.org/content/24/21/2445.full
