The pftools package is a collection of experimental programs supporting the generalized profile format and search method of PROSITE. A description of the generalized profile format is given in the file:
The official web site for the pftools package can be found under:
Further information on PROSITE specific applications of the pftools programs can be found at the following URL:
Release 2.3 contains FORTRAN 77 source code and manual pages for the following programs:
pfsearch
pfscan
psa2msa
gtop
htop
ptoh
pfmake
pfw
pfscale
ptof
6ft
2ft
Some supplementary manual pages describing the psa and xpsa file formats have also been included.
These programs have successfully been compiled and tested under Solaris, IRIX64, HP-UX, Tru64 and Linux operating systems, using the GNU g77 or f77 compilers.
For compilation with native f77 compilers, the Makefile needs to be modified according to instructions given therein.
For use under HP-UX, the file sterr.f should also be modified according to instructions given therein.
The buffer sizes in release 2.3 of the pftools have been significantly increased to handle large sequences and profiles. Therefore it might be necessary to reduce the buffer sizes in order to run the programs on machines with less RAM. This can be achieved by modifying the file ardim.f according to instructions given therein.
The "Integer2" declarations may cause problems with early versions of the g77 compiler; solution: replace "Integer2" by "Integer".
The compressed tar archive can be extracted to the current directory using the following command:
tar -xzvf pft2.3.tar.gz
This will create a directory containing the source and package files.
In order to compile the programs on Unix like systems with a FORTRAN 77 compiler, change into the source directory and simply type:
make all
This will create the 12 binaries listed above. To install the binaries and the corresponding manual pages, an installation script has been provided. It can be invoked using:
make install
The installation script will ask the user the destination directory for the pftools package. This directory will contain all the supplementary files, as well as a bin directory for the executable programs. The installer will then create symbolic links to the binary programs in a directory specified by the user. This directory should be included in the users PATH variable for him to be able to execute the pftools programs. In a last step, the installer will link the man pages in the system wide man page location, this location can also be specified by the user. After successful installation, the build directory can safely be deleted.
Note that you should have write permissions on the destination directories specified during installation. For system wide installation you may need root privileges, if necessary contact your system administrator.
Further included in this release are the following demo data files:
CVPBR322
sh3.seq
GTPA_HUMAN
sh3.msf
ecp.prf
sh3.gpr
sh3.prf
pfam_sh3.hmm
prosite13.prf
standard.random
blosum45.cmp
score.lis
coils.prf
MYSA_HUMAN
R76849.seq
plus the following additional substution matrices in old GCG format:
blosum30.cmp
blosum50.cmp
blosum62.cmp
blosum65.cmp
blosum80.cmp
blosum100.cmp
gonnet.cmp
pam30.cmp
pam40.cmp
pam80.cmp
pam120.cmp
pam160.cmp
pam200.cmp
pam220.cmp
pam250.cmp
pam400.cmp
A test script is provided. It will simply execute all the pftools binaries with some example files. The test script test.sh should be executed in the same directory as the binaries and the demo files. An example test output file test.out is provided as a reference. To test the programs, type:
./test.sh > out
diff test.out out
Some rounding or formatting variation may occur with real number editing. With g77 there will be lots of small integer rounding differences in the result of test 7.
Note that the file pfam_sh3.hmm contains a hidden Markov model from the PFAM A collection release 4.0 (see Pfam).
