[Geuvadis_rna_analysis] Re : [Geuvadis_rnaseq] Geuvadis LoF abstract for ASHG

by Tuuli Emilia LAPPALAINEN

Hello all, After some thought we've decided to add a couple of names to the author list of the LoF abstract. Our initial author list included people who are contributing specifically to LoF analysis, Natalja and Thasso for processing of the entire dataset, and the PIs and the Geuvadis Consortium representing the data. But it's fair to include one analysis person from all the labs on behalf of the data production, so we added Marc, Matthias, Olof, and Monkol from Daniel's lab. Thus, the latest version of the author list is the following: Manuel A Rivas, Tuuli Lappalainen, Michael Sammeth, Daniel MacArthur, Natalja Kurbatova, Thomas Wieland, Monkol Lek, Thasso Griebel, Matthias Barann, Marc Sultan, Olof Karlberg, Peter AC ‘t Hoen, Tim Strom, Stefan Schreiber, Hans Lehrach, Stylianos Antonarakis, Gert-Jan van Ommen, Ralf Sudbrak, Robert Häsler, Alvis Brazma, Ann-Christine Syvanen, Philip Rosenstiel, Thomas Meitinger, Roderic Guigo, Ivo Gut, Xavier Estivill, Mark McCarthy, Emmanouil T Dermitzakis, The Geuvadis Consortium best regards, Tuuli Le 01-06-12, Manuel Rivas <rivas(a)broadinstitute.org> a écrit : > Hello, > > Attached is an abstract that I am planning to submit on behalf of the project on loss of variants and their effect on the transcriptome.

[Geuvadis_rna_analysis] Geuvadis RNAseq abstract for ASHG

by Tuuli Lappalainen

Dear all, Enclosed please find a draft for the abstract that I'm planning to submit on behalf of the Geuvadis RNAseq project for the ASHG meeting in San Francisco. Comments are welcome; please send them by June 4th. The abstract has the maximum allowed number of authors (30) - at least one analyst per group and the PIs. I know there are many others who would deserve to be on that list, and apologies for not being able to include you here. In addition to this main abstract, there will be at least one sub-project abstract that will be sent around later. best regards, Tuuli -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch

[Geuvadis_rna_analysis] update to gencode v12

by Tuuli Lappalainen

Hello all, I'd like to update to Gencode v12 gene annotation (Ensembl 67) in the Geuvadis RNAseq project after all. After a lot of discussions, I'm now taking back my last week's decision to stick to v7. That would have made some things easier but others more difficult, and I wouldn't want us to lose any power because of an outdated annotation that might make a bit of a difference especially in the LoF variant annotations. It's not too late to switch yet - we'll need to rerun the transcript quantifications though. We'll let you know when it's done. No one expressed a strong opinion about this before, but if you disagree, please say it now. best regards, Tuuli -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch

[Geuvadis_rna_analysis] GEM bams available

by Tuuli Lappalainen

Dear all, Bam files from GEM are now available for download in /upload/geuvadis/wp4_rnaseq/main_project/sequence_data/bam/mrna/gem/ . These are big files so I strongly recommend using aspera; the command for downloading all the files of that folder would be like: cd /my/dir/for/geuvadis/bam/ ~/.aspera/connect/bin/ascp -QT -l 150M -k1 geuvadis@ah01.ebi.ac.uk:/upload/geuvadis/wp4_rnaseq/main_project/sequence_data/bam/mrna/gem/ . (this would create a folder gem/ in /my/dir/for/geuvadis/bam/ and download the files there. -k1 means that it will automatically skip downloading a file again if the name and size matches, which is very useful when you need to restart a download) best regards, Tuuli -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch

[Geuvadis_rna_analysis] geuvadis wiki updates: identifiers, formats and ASE

by Tuuli Lappalainen

Hello all, I've written some updates in the Geuvadis wiki: - I've created a page for identifier and file format information. We will all have less grey hair by the end of the project if we are consistent on these things. Please go and update those parts of data that concern you, and let people know of changes also by email - and check this page when creating data files! http://www.geuvadis.org/group/geuvadis/wikis/-/wiki/Main%20Geuvadis%20Wiki/… - I wrote quite a lot of text about ASE analysis - background information, summary of our pipeline, potential sources of error, available data, and a list of analysis that I'll keep on updating with results later on. http://www.geuvadis.org/group/geuvadis/wikis/-/wiki/Main%20Geuvadis%20Wiki/… best regards, Tuuli -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch

[Geuvadis_rna_analysis] analysis_data/quantification/transcript

by M.Sammeth

Dear all, we just replaced the transcript quantification files in analysis_data/quantification/transcript because we found that a script which counted the number of mapped reads for the RPKM normalization got confused by the whitespace characters inserted by the new casava/Illumina pipeline into the read IDs. Therefore, the RPKM values in the former files were off by ~ factor 2, the exact ratio old/new varies expectedly few % around the median 1.92 (plot attached). Hopefully this lapsus did not affect anybody's work--and please be careful not to run into the same issue when emplyoing programs that split columns by whitespaces on files with these read IDs; that was really a great idea of Illumina.

[Geuvadis_rna_analysis] allelic mapping bias fastqs ready

by Tuuli Lappalainen

Hi all - especially Thasso and Micha, In order to correct/filter for allelic mapping bias in Geuvadis analysis as we've discussed before, I've simulated reads over 1000g variants. The fastq files are available for mapping in /upload/geuvadis/wp4_rnaseq/main_project/external_data/genetic_variation/allelic_mapping_simulation/fastq . These should be mapped with GEM and converted to bam similarly to our real data, except that these are single-end reads. It actually became a lot less reads than I anticipated because I ended up taking only sites that are polymorphic in our populations: it's about 300M reads in total, so I hope that this could be done pretty soon :-) At least, could you please check already this week that the files are OK so that I can modify them if needed without further delay. Further details in the wiki: http://www.geuvadis.org/group/geuvadis/wikis/-/wiki/Main%20Geuvadis%20Wiki/… cheers, Tuuli -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch
