A restriction analysis tool.
tacg is a versatile tool for the restriction analysis of
nucleic acid sequences developed by Harry Mangalam at UC
Irvine. It allows to select the restriction enzymes by
type or by name or by the number of sites in the
sequence. It performs searches for nucleic acid patterns
and for open reading frames. See the tacg homepage for
further information about the software.
The CygWin port is based on tacg-3.04.
The source code is ANSI C and written to compile with gcc, so
the stuff compiles almost out of the box. The following
minor modifications are necessary:
regex.h is not part of CygWin, but it is shipped
with tacg. All references in the source files to <regex.h>
have to be changed to "regex.h". This holds true for
seqio.c needs three modifications. First, we have
to define __unix so the correct stuff gets included. Second, we
have to outcomment the definition of sys_errlist, as this is
provided by <errno.h>. Finally, we have to define
sys_errlist as _sys_errlist, as CygWin uses the latter version
with a leading underscore.
After building the software, run
strip tacg.exe to
reduce the size of the executable.
The following setup worked in my case:
- Windows NT 4.0 SP3 Workstation
- CygWin net release with Cygwin1.dll version 1.1.4
To install the software:
- copy tacg.exe into
- copy the files in the
/docs directories into one directory with read access for all users on the system, e.g.
- create a system-wide environment variable
TACGLIB and enter the directory of the previous step as a value
- copy the man page
tacg.1 into /usr/man/man1.
Get the original sources of tacg.
The precompiled binary for Cygwin 1.1.4 with the data files and
a diff file are shipped as cygwin1.1.4-tacg-3.04.tar.gz
