We are interested in
adding a link to your tool on the website. I have been playing around with
the tool but have been having some difficulty. I loaded the example, ran the
analysis and downloaded the results with no problem. Then, I tried to use
the data from the example to re-run the analysis by uploading the PF01036
fasta file (as an MSA) and listing BACR_HALSA as the reference sequence. I
did not load the tree data or the structure data. I submitted the request
and received the following error:
The coevolution analysis task that you submitted at 2013-09-11 11:35:07.0
could not be completed.
Error message:Not enough sequences.
In order to justify the addition of the link to the website, we need to make
sure that the web interface is simple and easy to use. Can you help me
understand what the problem might be (clearly I have enough sequences since
the example runs without any issues)? Also, can you explain to me the link
between the 1C3W reference structure and the sequence data?
Any help you can give would be greatly appreciated.
The error message is due to an internal check of the system. Since
coevolution analysis requires a good number of sequences to give
reliable statistics, there is a minimum threshold of the number of
sequences after the filtering step. When the example is loaded, I think
some of the filtering settings are made so that it can pass the minimum
threshold. When one manually uploads the MSA, the default settings could
You may try changing the setting for the minimum number of
sequences in the "Advanced options" section (which is by default hidden)
and rerun. Let me know if you still get any error message.
