Add a Characteristic

1. On top of the annotation table, open the Add Building Block widget .

2. From the dropdown menu select Characteristic. The order of blocks shown below may not correspond to what you see in ARCitect but we will learn how to rearrange columns later.

3. Enter organism in the search bar. This search looks for suitable terms in the ontology database.

4. Select the Term with the id OBI:0100026 and click Add Column.

5. In the table, insert values by selecting any cell below Characteristic [organism].

   

   I worked on Arabidopsis thaliana plants

6. Search for Arabidopsis thaliana, select a suitable hit and again fill the complete column with right-click on a cell and select Fill Column.

   Input[Source Name]	Characteristic [organism]	Output[Sample Name]
   Cold1	Arabidopsis thaliana	Cold1_leaf
   Cold2		Cold2_leaf
   Cold3		Cold3_leaf
   RT1		RT1_leaf
   RT2		RT2_leaf
   RT3		RT3_leaf

   

   Great, I’ve got this! Now I can add building blocks for the characteristics “tissue” and “growth medium” and enter the values “leaf” and “hydroponic plant culture media”, respectively.
