READ_ALIGN
Convert an alignment to PIR format

READ_ALIGN is a FORTRAN77 program which reads a file containing information about a multiple sequence alignment, and writes out the relevant information to another file using the PIR format, by Des Higgins.

The reason for converting to the PIR format is to use the DISTANCES program.

Languages:

READ_ALIGN is available in a FORTRAN77 version and a FORTRAN90 version.

Related Data and Programs:

DISTANCES, a FORTRAN77 program which can read a file in PIR format and create a distance matrix.

SPACER, a FORTRAN77 program which can read a distance matrix and perform a principal component analysis.

SPACER_DATA_CONVERT, a FORTRAN77 program which can read a multiple sequence alignment file and write out the relevant information into a file in PIR format.

Source Code:

• read_align.f, the source code;
• read_align.sh, commands to compile and load the source code;

Examples and Tests:

• clustal.dat, a CLUSTAL alignment file;
• clustal.pir, the converted alignment file;

List of Routines:

• READ_ALIGN reads a multiple alignment file and rewrites it in PIR format.
• BLANK_LINE looks for a "blank" line.
• TIMESTAMP prints the current YMDHMS date as a time stamp.
