**Syntax**

This tools performs common operations (such as summing, counting, mean, standard-deviation) on input file, based on tabular data. The tool can also optionaly group the input based on a given field.

-----

**Example 1**

- Find the average score in statistics course of college students, grouped by their college major. The input file has three fields (Name,Major,Score) and a header line::

    Name        Major            Score
    Bryan       Arts             68
    Gabriel     Health-Medicine  100
    Isaiah      Arts             80
    Tysza       Business         92
    Zackery     Engineering      54
    ...
    ...

- Grouping the input by the second column (*Major*), sorting the input, and performing operations **mean** and **sample standard deviation** on the third column (*Score*), gives::

    GroupBy(Major)     mean(Score)   sstdev(Score)
    Arts               68.9474       10.4215
    Business           87.3636       5.18214
    Engineering        66.5385       19.8814
    Health-Medicine    90.6154       9.22441
    Life-Sciences      55.3333       20.606
    Social-Sciences    60.2667       17.2273

Note that input needs sorting here, since the column used for grouping (*Major*) is not sorted.

**Example 2**

- Using the UCSC RefSeq Human Gene Track, available at: http://hgdownload.soe.ucsc.edu/goldenPath/hg38/database/refGene.txt.gz

- List the number and identifiers of isoforms per gene. The gene identifier is in column 13, the isoform/transcript identifier is in column 2. Grouping by column 13 and performing **count** and **Combine all values** on column 2, gives::

    GroupBy(field-13)     count(field-2)     collapse(field-2)
    A1BG                  1                  NM_130786
    A1BG-AS1              1                  NR_015380
    A1CF                  6                  NM_001198818,NM_001198819,NM_001198820,NM_014576,NM_138932,NM_138933
    A2M                   1                  NM_000014
    A2M-AS1               1                  NR_026971
    A2ML1                 2                  NM_001282424,NM_144670
    ...

- Count how many transcripts are listed for each chromosome and strand. Chromosome is on column 3, Strand is in column 4. Transcript identifiers are in column 2. Grouping by columns **3,4** and performing operation **count** on column 2, gives::

    GroupBy(field-3)     GroupBy(field-4)     count(field-2)
    chr1                 +                    2456
    chr1                 -                    2431
    chr2                 +                    1599
    chr2                 -                    1419
    chr3                 +                    1287
    chr3                 -                    1249
    ...
