Summary

0000190: Error message during model selection

Description

I am reporting an error message that I recently got using the MEGA-CC program on a Mac 10.11 system with 16GB ram and 1 TB harddisk space. I was running the Models selection option using MEGA-CC for 108 protein sequences (average length 1619 aas). I am attaching the .meg file and the exact message in the Additional Information section.

Steps To Reproduce

Commands used:

megacc -a model_sel_ml_protein.mao -d Listeria101.meg -o Listeria.txt

model_sel_ml_protein_mao is the settings after selecting for Model selection on proetin alignment using default settings

Additional Information

Listeria.txt:

; Error: The current analysis cannot be completed because Mega is not able to
allocate sufficient memory from the system. This is not an error but
rather a limitation due the intensive memory requirements of the calculation
requested and the data used.:
