Phenotype Search
Provide a list of genes and see if any have an allele presenting a given phenotype keyword.

If any of your genes have alleles that have the provided keyword in the phenotype description, the gene will show in the output along with the alleles showing that phenotype.
Convert Gene Symbol to FlyBase IDs
Convert gene symbols to current Flybase IDs and vice-versa.

Paste in your list of gene symbols or FBgn IDs and convert!
Genetic Interactions Search
Find if a given gene has any known genetic interactions with a list of any number of genes.

Enter your gene of interest as the main gene, paste in your list of genes to compare against (e.g. genes from a transcriptome analysis) and search.
Protein Interactions Search
Find if a given protein has any known protein interactions with a list of any number of proteins.

Enter your protein of interest (as case sensitive Gene Symbol) as the main protein, paste in your list of (case sensitive) Gene Symbols to compare against and search.
 
Protein Interacting Pairs
Find if there are any known protein-protein interacting pairs from a given list of proteins.

Paste in your list of (case sensitive) Gene Symbols to compare against and if any of the proteins in the list are known to interact with any of the others, the interacting pair will be shown in a format compatible with Cytoscape.
FlyBase ID to BED file
Create a genomic BED file from a list of Flybase IDs.

Paste in your list of FBgn IDs and convert to BED-formatted genome positions.
Using the option "Convert FBgn's to gene symbol" will output the gene symbol in the BED file, rather than the FBgn ID.
Human disease Models
Find if any given genes have alleles that are used as a model for human diseases.

Paste in your list of genes and find if any of them have alleles used as models of human diseases.
