Good job! Thanks for a wonderful program!

>> ready to be imported into spreadsheet programs.
>>
>> As a lot has changed since the 2.8.x series of MIRA, the following list
>> has just a few highlights which came in during the 2.9.x series:
>>
>> - sequencing technologies: MIRA handles different sequencing technologies
>> independently from each other and has specialised routine for working
>> with
>> each of them.
>> - command-line parameters: MIRA has now a handful of "Do-What-I-Mean"
>> one-stop
>> switches which allows to configure the assembler for 90% of all use
>> cases. Furthermore, many parameters can be adjusted for each sequencing
>> technology so that the assembly engine can be tweaked for very
>> specialised
>> cases if needed.
>> - all sequencing technologies (Sanger, 454, Solexa) have now
>> - recognition of chimeras
>> - new assembly routines to for improved repeat resolving
>> - improved data preprocessing that gets rid of low quality data and
>> sequencing errors at ends of reads ... even when no quality data is
>> available.
>> - 454 data:
>> - fully developed capability for de-novo and mapping assembly of 454 data
>> (paired and non-paired)
>> - automated contig editor to remove most obvious and/or annoying
>> sequencing
>> errors
>> - improved consensus calling streamlined to minimise the dreaded
>> homopolymer
>> problem
>> - Solexa data
>> - can handle Solexa data of any length, no restriction to very short
>> sequences.
>> - memory/space saving: MIRA has special mapping mode which creates data
>> so that widely used finishing tools like gap4 and consed can load these
>> projects and still be fairly quick
>> - alignments enriched with features: MIRA adds information like
>> repetitiveness
>> or repeat marker bases as tags in the assembly so that these can be used
>> during finishing
>> - assembly information files: MIRA writes more information files which can
>> be
>> easily parsed and/or read
>> - mapping assemblies: MIRA has a full SNP analysis for prokaryotic data
>> - comprehensive tables and HTML result files (mapping assembly): the
>> convert_project program can now create easy to use tables and HTML files
>> which show the data in a way suited for less computer-interested people
>> (biologists etc. :-)
>> - memory management: MIRA can now be told to use an upper limit of RAM.
>> - file formats: MIRA can now parse or write more file formats. Notable are
>> change from SSAHA to SSAHA2 for clipping, FASTQ for data input and MAF
>> format for output.
>> - MacOS support: MIRA now compiles on MacOS-X
>> - speed and memory: compared to 2.8.x, MIRA now uses way less memory and
>> is a
>> lot faster.
>> - tons of other features, tweaks and bug fixes. See the CHANGES_old.txt
>> file
