Hi: Thanks for the quick answer. I just did what you suggeested me. and change the files to the _in.454.fasta format, for all of them (the quality file and the backbone too). However I am still getting an error with the backbone file ---> Fatal Error (may be due to problems of the input data): "File not found: 454_muestra2_backbone_in.fasta" ->Thrown: size_t ReadPool::loadDataFromFASTA(const string & filename, const uint8 loadaction, uint32 & longestread, const bool wantsqualfiletoexist, const string & qualfilename, const bool generatefilenames, const uint8 seqtype, const bool sxa_mustconvert) ->Caught: main Program aborted, probably due to error in the input data or parametrisation. Please check the output log for more information. For help, please write a mail to the mira talk mailing list. CWD: /home/homes/users/fsanchez/MIRA_ASSEMBLY Aborted My command line is the same but changing the backbone file to backbone_in.454.fasta instead of the 454_muestra2_backbone_in.fasta, what else could be going wrong? any suggestions?. At the moment I am not able to download the newer versions of mira but I hope mira 3.0.0 is up for the task. /aplic/mira-3.0.0/bin/mira -fasta -project=454_muestra2 -job=mapping,genome,normal,454 --noclipping=all --notraceinfo COMMON_SETTINGS -AS:sd=yes -SK:mnr=no -SB:lb=yes:bsn=454_muestra2_backbone_in.454.fasta:bbq=100:bft=fasta:abnc=yes Thanks again for the help Federico On Mon, Mar 15, 2010 at 11:36 AM, Jan Paces <hpaces@xxxxxxxxxx> wrote: > On 03/15/10 04:56, Federico Sanchez wrote: > > 1) /aplic/mira-3.0.0/bin/mira -fasta -project=454_muestra2 > > -job=mapping,genome,normal,454 --noclipping=all --notraceinfo > > COMMON_SETTINGS -AS:sd=yes -SK:mnr=no > > -SB:lb=yes:bsn=454_muestra2_backbone_in.fasta:bbq=100:bft=fasta:abnc=yes > > For mapping, I suggest to use mira-3.0.3, there were some problems with > parsing input data in version 3.0.2 a maybe lower as well, I am not sure. > > As for the error with input files, you need _in.454. in the names - > as pointed out by Sven befora I sent this email ;-) > > Jan > > -- > You have received this mail because you are subscribed to the mira_talk > mailing list.
