Dear colleague,
I have met a problem with your assembly converter :

I try to convert V4 to V2 :
First I select AGPV4 -> AGPV2
Then, i write in the field "Either paste data" : 
chr1 35000 35800

And It fails with the following message :
"Error: Uncaught exception 'HiveException' with message 'Output file empty (zero bytes).' Thrown by EnsEMBL::Web::RunnableDB::AssemblyConverter::run in module Bio::EnsEMBL::Hive::Process at /usr/local/ensembl-86/ensembl-hive/modules/Bio/EnsEMBL/Hive/Process.pm on line 140 Called by (eval) in module Bio::EnsEMBL::Hive::Process at /usr/local/ensembl-86/ensembl-hive/modules/Bio/EnsEMBL/Hive/Process.pm on line 127 Called by Bio::EnsEMBL::Hive::Process::life_cycle in module Bio::EnsEMBL::Hive::Worker at /usr/local/ensembl-86/ensembl-hive/modules/Bio/EnsEMBL/Hive/Worker.pm on line 688 Called by (eval) in module Bio::EnsEMBL::Hive::Worker at /usr/local/ensembl-86/ensembl-hive/modules/Bio/EnsEMBL/Hive/Worker.pm on line 674 Called by Bio::EnsEMBL::Hive::Worker::run_one_batch in module Bio::EnsEMBL::Hive::Worker at /usr/local/ensembl-86/ensembl-hive/modules/Bio/EnsEMBL/Hive/Worker.pm on line 526 Called by Bio::EnsEMBL::Hive::Worker::run in module Bio::EnsEMBL::Hive::Scripts::RunWorker at /usr/local/ensembl-86/ensembl-hive/modules/Bio/EnsEMBL/Hive/Scripts/RunWorker.pm on line 85 Called by (eval) in module Bio::EnsEMBL::Hive::Scripts::RunWorker at /usr/local/ensembl-86/ensembl-hive/modules/Bio/EnsEMBL/Hive/Scripts/RunWorker.pm on line 94 Called by Bio::EnsEMBL::Hive::Scripts::RunWorker::runWorker in module main at /usr/local/ensembl-86/ensembl-hive/scripts/runWorker.pl on line 135 Called by main::main in module main at /usr/local/ensembl-86/ensembl-hive/scripts/runWorker.pl on line 23

Do you have an idea on what's happened ?
