Viability is usually determined under standard laboratory conditions, i.e. a cell is generally considered inviable if it cannot grow in rich medium under normal conditions such as temperature, pressure, oxygen level, pH, etc. Note that if you have done an experiment that assays the viability of a population of cells, such as looking at colony growth or growth in liquid culture, you should also annotate to 'inviable cell population' (FYPO:0002059) or one of its descendants. This is a high-level term whose primary purpose is to organize terms beneath it in the ontology, and we expect that it will not be used for direct annotations. Please consider using a more specific term to annotate each phenotype.
