solar2mloci: Convert a directory of SOLAR-formatted ibd and/or mibd files...

In multic: Quantitative Linkage Analysis Tools using the Variance Components Approach

Description

solar2mloci reads all of the ibd and mibd files in the given directory, and creates mloci.out.gz in the specified output directory.

Usage

solar2mloci(directory, phi2, pedindex.out, pedindex.cde,
          ibd.dist = NULL, output.directory = ".",
          delete.fixed.dir = TRUE)

Arguments

directory	charater value specifying a path to a directory of SOLAR-formatted ibd and/or mibd files. These files are often kept in .gz format. solar2mloci will manage this for the user.
phi2	charater value specifying a path to a SOLAR-formatted phi2 file. Due to the general size of a typical phi2 file, it is often stored in .gz format. solar2mloci will manage this for the user. Whether the user specifies the file with a .gz suffix or not will not effect how solar2mloci operates on the file.
pedindex.out	character value specifying a path to a SOLAR-formatted pedindex.out file. This must be the same file that was output from SOLAR. It provides a mapping between the sequential number system assigned by SOLAR and the original family and individual identifiers.
pedindex.cde	character value specifying a path to a SOLAR-formatted pedindex.cde file. This must be the same file that was output from SOLAR. This file describes the format of pedindex.out. This is necessary to read pedindex.out correctly.
ibd.dist	charater value specifying a path to a SOLAR-formatted .dist file that maps the character marker names of ibd files to their corresponding numeric centimorgan values.
output.directory	charater value specifying a path to a directory where the output file mloci.out.gz will be created. If the directory (including supporting path) does not exist yet, it will be created. Also, solar2mloci will overwrite mloci.out and mloci.out.gz if they exist in output.directory.
delete.fixed.dir	logical flag: if TRUE, delete the temporary directory used to "fix" the SOLAR-formatted ibds and mibd files. This is mostly for debugging purposes and is very likely to be not useful to the user community.

Side Effects

Due to write permissions possibly not allowing the user to gunzip and create files in the specified directory, solar2mloci first copies directory and phi2 to the current directory. solar2mloci then creates a temporary directory to hold the "fixed," intermediate files that will be deleted (by default). Also, solar2mloci will overwrite mloci.out and mloci.out.gz if they exist in output.directory.
