Acesso em: .https://bdm.ufpa.br/handle/prefix/8525The STRUCTURE software has gained popularity as a tool for population structure and genetic analysis. However, formatting data to meet specific STRUCTURE requirements can be extremely cumbersome and error-prone, especially when dealing with multilocus data. This article highlights the creation of a graphical user interface (GUI) application tailored to streamline the process of converting multiple sequence alignments into a single, cohesive file that is compatible with the STRUCTURE software. The application has been developed utilizing Tkinter for the GUI and Biopython for handling FASTA files. This program processes the files, pinpoints variable sites, and converts the sequences into a binary format. Subsequently, the sequences are concatenated and presented within the graphical interface's text area, enabling users to review and confirm the results. Furthermore, the program stores the concatenated results in a file, delivering a ready-to-use input for the STRUCTURE software. This application offers an efficient and dependable solution for transforming multiple aligned FASTA files into a concatenated binary format file, which is compatible with the STRUCTURE software. With its user-friendly graphical interface and error-reducing approach, this tool proves invaluable to researchers conducting research in the field of population structure and genetic analysis.Acesso AbertoAplicação GUIGenética populacionalDados multilocusTkinterBiopythonSequências alinhadasGUI applicationPopulation geneticsMultilocus dataTkinterBiopythonAligned sequencesCNPQ::CIENCIAS BIOLOGICAS::GENETICATrabalho de Curso - Graduação - ArtigoAttribution-NonCommercial-NoDerivs 3.0 Brazil
