1. Copiar o ficheiro de entrada (formato .txt) para a pasta onde se encontra o programa executável que vai utilizar (ex: restdist.exe).

2. Clicar duas vezes sobre o executável para abrir o programa.

3. Escrever o nome do ficheiro de entrada (não esquecer a extensão “.txt”).

4. Alterar as opções pretendidas conforme indicado no menu.

5. Escrever ‘y’. Automaticamente é gerado um ‘outfile’ e/ou um ‘treefile’.

6. Transferir estes ficheiros para outra pasta e mudar-lhes o nome.

7. Abrir o ficheiro ‘treefile’ com o programa TreeView para analisar a árvore produzida.

Sequência de passos para utilizar o programa MrBayesMrbayes.exe

1. Gravar o ficheiro de entrada na mesma localização que o programa executável.

2. Iniciar o programa.

3. Escrever o comando ‘execute’ e depois o nome do ficheiro de entrada (não esquecer a extensão ‘.txt’).

4. Aumentar o número de gerações para 1 000 000.

5. Verificar se ao fim deste nº de gerações o valor do desvio padrão entre as cadeias é ≤ 0.01.

6. Se sim pode parar o programa.

7. Escrever o comando ‘sump burnin = 2500’ (resumir os valores dos parâmetros).

8. Escrever o comando ‘sumt burnin = 2500’.

9. Verificar o resultado abrindo o ficheiro com extensão ‘.con’ com o programa TreeView.
