 [[https://github.com/BIONF/fCAT|fCAT]] is a **f**eature-aware **C**ompleteness **A**ssessment **T**ool, that helps to answer the question "How complete is my gene set?". In particularly, fCAT checks for the presence of conserved genes (the core genes) of a specific taxonomy clade in the target gene set using feature-aware directed ortholog search ([[https://github.com/BIONF/fDOG|fDOG]]). In addition to the length criteria for classifying the found orthologs (as same as [[https://busco.ezlab.org/|BUSCO]]), fCAT utilizes the domain architecture similarity [[https://github.com/BIONF/FAS|FAS scores]] to further validate the orthologs. The later gives an alternative view on the accuracy of the target gene models, which shows how different the target orthologs in comparison to the core genes in their domain architecture. [[https://github.com/BIONF/fCAT|fCAT]] is a **f**eature-aware **C**ompleteness **A**ssessment **T**ool, that helps to answer the question "How complete is my gene set?".

-fCAT outputs both the summary result in a tabular text file and the phylogenetic profile of the core genes, which can be visualized using the tool [[https://github.com/BIONF/PhyloProfile|PhyloProfile]]. By analyzing the profiles of the entire orthologous groups within a specific taxonomy clade, we can further identify and ultimately correct erroneous gene annotations.  +fCAT outputs both the summary result in a tabular text file and the phylogenetic profile of the core genes, which can be visualized using the tool [[https://github.com/BIONF/PhyloProfile|PhyloProfile]].

 The table below explains how the //specific ortholog group cutoffs// for each fCAT core set were calculated, and which //value of the query ortholog// is used to assess its completeness, or more precisely, its functional equivalence to the ortholog group it belongs to. If the value of a query ortholog is //not less than// its ortholog group cutoff, that group will be evaluated as **similar** or **complete**. In case co-orthologs have been predicted, the assessment for the core group will be **duplicated**. Depending on the value of each single ortholog, a //duplicated// group can be seen as **duplicated (similar)** or **duplicated (dissimilar)** in the full report (e.g. *all_full.txt*). The table below explains how the //specific ortholog group cutoffs// for each fCAT core set were calculated, and which //value of the query ortholog// is used to assess its completeness, or more precisely, its functional equivalence to the ortholog group it belongs to.
