Program extracts any number of columns (and in any order) out of a machine readable table using the information in the metaheader. The program can be used to create a new table from the original machine-readable table that is Tab delimited and thus easily read into spreadsheet programs like EXCEL. The options flags that are Currently available are:

 

  • -c#,#,#,...,# : which extracts out the columns numbers given after the -c flag. Each column number needs to be separated by a comma

  • -d(tab|amp) : specifies the type of delimiter used to seperate the columns. Use tab for a TAB delimiter and amp for &s

  • -latex : outputs the data in a LaTeX/AASTex style table.

  • -p : print out the metadata header only

  • -help : print this help message and quit.

 

The last arguement has to be the machine readable file.

 

The syntax is:

extractcols.pl -opt1 .... -opt# file

          or
  
extractcols.pl -opt1 .... -opt# file > newfile

to capture the output to a file called newfile.

 

Program has been sucessufully compiled and tested with Perl v5.6.0 built for sun4-solaris running on a SUN Ultra 10. NOTE YOU MUST CHANGE THE FIRST LINE IN THIS CODE TO POINT TO THE LOCAL VERSION OF PERL ON YOUR MACHINE FOR THIS TO WORK!
