[ensembl-dev] ENSEMBL INSTALLATION ISSUE: Regulation AJAX error

[Rafael Hernández]

Hi,

I've installed a local version of Ensembl release 70 following the provided
documentation and everything works fine except the Regulation tools
(example<http://www.ensembl.org/Homo_sapiens/Regulation/Cell_line?db=funcgen;fdb=funcgen;r=17:46617590-46621119;rf=ENSR00001348194>
of
regulation tool).
When I query Ensembl looking for regulation info, it produces an AJAX error
and no graphics are showed.
Below the error message:

*AJAX error - Runtime Error in component
EnsEMBL::Web::Component::Regulation::FeaturesByCellLine [content]"*
Function EnsEMBL::Web::Component::Regulation::FeaturesByCellLine fails to
execute due to the following error:

 -------------------- EXCEPTION --------------------
MSG: Failed to open:
 ...
/result_feature/GM12878_DNase1_ENCODE_Uw/result_features.GM12878_DNase1_ENCODE_Uw.130.col
No such file or directory


I know the cause of the problem: Ensembl tries to read some files from a
directory located in the root of the file system  (e.g.
 /result_feature/GM12878_DNase1_ENCODE_Uw/result_features.GM12878_DNase1_
ENCODE_Uw.130.col), however the directory /result_feature/ doesn't exists
and the query crashes.

If I move the /result_feature/ folder to the root of my file system, then
Ensembl works, however I don't want to put there those files, and I want to
know how could I change this. I found in the ensembl-dev page a thread
talking about this problem
(here<http://lists.ensembl.org/pipermail/dev/2012-April/007279.html>)
and they suggested to set a variable ENSEMBL_REGULATION_FILE_PATH pointing
to the desired folder in the DEFAULT.ini file.
In my case should look like this:

 ENSEMBL_REGULATION_FILE_PATH=/usr/local/ensembl/regulation_files/

However it doesn't works. Nothing change when using this setting and
Ensembl still looking for the files in the previous directory. Any idea?

Thank you and best regards,
