Dear Marek, You can find a manual on how to use the artemis tool on the Sanger Institute website. May I inquire if you find the artemis tool itself not user-friendly or rather the way it is incoporated in the portal? The coordinates in the artemini view differ indeed from the ones on the webpage. this is because the sequence you get to see in the artemini view is only a subpart of the whole scaffold (this in order to let the procedure go faster). The coordinates you see in artemini are in reference to the subpart while you have (and also on the webpage) them in reference of the whole scaffold. In theory it is possible to make the coordinates 'box' editable. but, ... i'm a little bit reluctant to do this due to bad experience with this approach in previous projects. We noticied it is very easy to include mistakes this way (aspecially for non experienced annotators). That is why we include the artemini system in this version (where some basic checks on the structure are performed and you have the visual check of the structure). But I also completely understand your point that for more experienced users this might not be ideal... What we also can do is to add a function in the artemini to 'transfer' the coordinates you enter (in reference of the whole scaffold) onto the subpart in artemini. That way you could just paste your coordinates into the coordinate box of artemini, push the 'transfer' button and they will be adjusted onto the subpart. You can then also profit from the visual check. When you then save your modifications they will be entered to the DB. Do you think this might be more useful? or does it still sounds to much of a hastle? best and thanks for the feedback, lieven > Dear Lieven, > > thanks for the link, I have successfully downloaded the protein > database. I would like to start making corrections of the gene models I foud to be incorrectly predicted ion the rpesent annotation. Is there any manual how to work with the Artemini tool? I found it not be too user-friendly. For instance, I do not understand why the exon coordinates indicated by Artemini differs from the actual coordinates on supercontigs? Just take the gene Esi0425_0013. The present > coordinates, with an incorrect first exon, are as follows: > > 47430..47455,47682..47802,48669..48716,49305..49400,50478..50556,51041..51197,53081..53171 > > I would like to change the first exon so that the coordinates are like this: > > 45460..45476,47682..47802,48669..48716,49305..49400,50478..50556,51041..51197,53081..53171 > > The coordinates given for this gene in Artemini are as follows: > > 3555..3580,3807..3927,4794..4841,5430..5525,6603..6681,7166..7322,9206..9296 > > Why there is the difference?

from Mark, .... My browser has a bit of trouble paging through the protein alignment graphic in the protein homologues section, is this a big image (in terms of resolution?) It doesn't seem to be possible to search for an amino acid or nucleotide motif in Artemini using the goto menu. Is this normal? This makes it quite dificult to find specific regions with possible structural problems. ??
