can't obtain the final pivot web browser view with alignement of DNA sequence


Dear all

i'm triying to align a DNA sequence, the process ends correctly, but the browser doesn't show nothing.
i have already enable popup windows in the web browser originating from address and i have too cleared the web browser cache and delete web browser cookies. but the results are the same. i have probed the same result in google chrome and IE.
I think BL!P give all the required files to obtain the correct view.

I attached a snapshot of the final browser result and another with the parameters that i have used for these process.

PD: i'm using BL!P v20

Sorry you are having trouble.

What version of windows are you running?

Did you see a rotating blue wheel in the web browser prior to the blank page?

Have you installed all the requirements for making this work in a web browser?
Microsoft Silverlight
Microsoft Silverlight PivotViewer Control
If running BL!P as a non-admin user, did you get prompted for access for lauching the local webserver ("Allow access" dialog). If so, did you allow access?

hi vince,

i'm running over windows 7, in the initial step I look something like the next attached snapshot, this is just for a few seconds, after, i get the a blank page just like the last image (BLIP_3_parameters.jpg), and no, i can't see the silverlight load wheel.

yes i have installed all the requeriments including silverlight and PivotViewer (i have downloaded of this page:, and lastely i'm the administrator of my windows user account. and never request me "Allow access" dialog, because i'm the admistrator so everything is allowed for me.

waiting for your answer,

Hi Leonardo,

Does loading other PivotViewer demos work, like the ones found here:

If not we can discuss this at length via personal email. I will post the solution here when we find one.

I can reproduce the results you get by doing this:
  1. When accessing a public bl!p demo I made at:

and changing the url to:
  1. For a locallay running bl!p this works:

but this does not:


Maybe it is something with you web server configuration?

Maybe try to replace with localhost?

I have tried your suggestion, but i have the same results, so i have instaled and configured IIS7 correctly again, because i was thinking that IIS maybe was the responsable. but let me tell you, my IIS is running correctly. i don´t know if this issue is due to the version of .NET Bio that i'm actually using, because BLIP uses MBF.

PD: My localhost works correctly with localhost and (see the attached image)

Now i have executed run BLIP, with and without IIS, and the results are the same

another suggestion?

pd: I know BLIP has his own server

How big is the blip project that you are testing? If not too big, zip it and send it to me by whatever way you want.

If too big, can you create a smaller one with fewer query sequences and sent it to me.
