Hi Marek,

We'll look into it. any possibility you can give us (preferably the english translation ;-) )the czech error message?

thx, lieven

Hil Lieven,

I would like to place some text on "my" page in the Ectocarpus Wiki site (the link "G Proteins" on the main page). When I put the text into the window (invoked by pressing "Create this page") and press "Save", teh browser swithc to a page with a Czech error report, whcih after reloding changes to a page sayin "Sorry, you don't have enough rights to continue. Perhaps you forgot to login?". However, I am logged. Could you, please, look at this problem? Thanks, Marek

Hi Marek,

I fear you just demonstrated why we use the artemini as a check (in stead of making the coordinate box on the webpage editable) :-[ : there is an error in the coordinate set you provide: ...... ,439639..439695,440076..440186,440581..440670,441533..441669,4422224..442297,442889......... artemini complains because the seq is only ~1.2Mb long and your coordinate is ~4.4Mb .

grtz, lieven

Hi Lieven,

it seems that you indeed partially solved the problem with saving exon coordinates as I now could save the coordinates of the gene Esi0031_0121 using the pption 'Modify Using Artemini (full sequence)'. However, even this option does not work for the gene Esi0008_0081, which should actually be merged with the gene Esi0008_0082 so that the coordinates should be as follows:

435416..436165,437250..437506,437809..437896,438082..438272,438896..439229,439639..439695,440076..440186,440581..440670,441533..441669,4422224..442297,442889..442998,443534..443650,444305..444505,445069..445218,445540..445680,446186..446371,447092..447184 The error message is still the same - it is out of the range of the sequence. Could you, please, have a look on this? thanks, Marek

Hi Marek,

We solved this the following way: You now have a choice between 2 possible downloads in artemini: small sequence (as it was) and the whole sequence ('Modify Using Artemini (full sequence)' ). With the whoel sequence you should have the problem anymore (but it can take longer to download it).

grtz, lieven

Hi Lieven,

I onece more cannot save coordinates of a gene moeld edited in Artemini. I need to save the following coordinates for the gene Esi0031_0121:

650149..650208,650956..651132,651761..651904,652788..652932,653394..653455,654128..654328,654791..654934,655760..655847,662896..663023,663661..663789,664631..664729,665569..665796,666203..666318,666898..667006,667469..667526,668411..668577,669887..670197,670893..670998,672023..672127,672633..672761,673309..673461,674180..674335,675415..675510 When I put them to the respective widow and press "OK", the following error announcement appears:

Cannot apply changes because of location error: Parse error at this point: ..664729,665569..665796,666203..666318,666898..667006,667469..667526,668411..668577,669887..670197,670893..670998,672023..672127,672633..672761,673309..673461,674180..674335,675415..675510)): garbage at the end of the location string

Could you, please, have a look on this?
