Csvtk - Filter Help
-------------------

Info
####

Csvtk filter outputs rows that satisfy an input numerical expression on the specified column(s).

.. class:: warningmark

    Single quotes are not allowed in text inputs!

Usage
#####

**Ex. Filter on one column:**

Suppose we had the following table:

+---------------+------------+----------+
| Culture Label | Cell Count | Dilution |
+===============+============+==========+
| ECo-1         | 2523       | 1000     |
+---------------+------------+----------+
| LPn-1         | 100        | 1000000  |
+---------------+------------+----------+
| LPn-2         | 4          | 1000     |
+---------------+------------+----------+

If we used the filter expression "Cell Count>100", we would get the following output column:

+---------------+------------+----------+
| Culture Label | Cell Count | Dilution |
+===============+============+==========+
| ECo-1         | 2523       | 1000     |
+---------------+------------+----------+

----

**Ex2. Filter on two columns:**

Same input table

+---------------+------------+----------+
| Culture Label | Cell Count | Dilution |
+===============+============+==========+
| ECo-1         | 2523       | 1000     |
+---------------+------------+----------+
| LPn-1         | 100        | 1000000  |
+---------------+------------+----------+
| LPn-2         | 4          | 1000     |
+---------------+------------+----------+

Now if we use the expression "2-3>50" to filter on, we would pull out:

+---------------+------------+----------+
| Culture Label | Cell Count | Dilution |
+===============+============+==========+
| ECo-1         | 2523       | 1000     |
+---------------+------------+----------+
| LPn-1         | 100        | 1000000  |
+---------------+------------+----------+

Row 3 is not returned back as its column 2 is not greater than 50. 

However, if **Any** is set to Yes, then Row 3 would be returned as its column 3 is greater than 50
making it satisfy one part of the expression.


**Note:** - Multiple columns can only be specified with a "-"
