How can I save my alignment to a file?

The alignment will appear on the results page along with details of scores and guide trees. The alignment can be obtained on its own by clicking on the alignment file option at the top (.aln). This file can be opened in a separate window or saved to a file.

Is there a limit on the number of sequences or the size of the file that I submit to ClustalW?

The input for ClustalW is limited to a maximum of 500 sequences or to a 10MB file (whichever is smaller). When the input file or the number of sequences is large, ClustalW can run for days and in some cases may not finish at all. If you plan to input large amounts of data/sequences, you should use the "RESULTS: email" option and "CPU MODE: multiple".

Email jobs are allowed to run for more than 24 hours and the results are kept for a week.
