bedtools:tldr:b6f90
The command bedtools groupby
is a tool used in bioinformatics to group genomic intervals by a specified attribute.
Here's the breakdown of the command:
-
bedtools groupby
: This is the main command that tells the tool to perform the grouping operation. -
-i ${filename}
: This parameter specifies the input file on which to perform the grouping operation.${filename}
is a placeholder for the actual filename. You need to replace it with the actual name of your input file. -
-c 1-3,5
: This parameter specifies the columns in the input file to use for grouping. Here, columns 1, 2, 3, and 5 will be used. -
-g 6
: This parameter specifies the column in the input file that contains the attribute to group by. In this case, column 6 will be used. -
-o sum
: This parameter specifies the operation to perform on each group. In this case, it will calculate the sum of the values of the grouped intervals.
Overall, this command will take an input file, group the genomic intervals based on the values in column 6, and calculate the sum of the values in columns 1, 2, 3, and 5 for each group. The output will contain the grouped intervals and the corresponding sum values.
