FAANG 2022 Workshop Zoom Chats

Session I

00:34:37Angelica Van Goor:Thank you to the organizers for making this meeting happen despite the (continuing)challenges.
00:38:53PARVAZ SARFARAZ:thank you
00:41:16Christopher Tuggle:@PeterHarrison Is there a current effort on a nf-core for scRNAseq or scATACseq?
00:44:34PARVAZ SARFARAZ:ldont know what you mean
00:45:12PARVAZ SARFARAZ:peter
00:50:21Christopher Tuggle:Thanks- will follow up!
00:53:19Hans Cheng:Nomenclature can be an issue. Are you working with journals to aid the best use?
00:58:34Emily Clark:**Please post your questions for the speakers here rather than the Q&A box**
00:59:13PARVAZ SARFARAZ:ok thanks for you gudance🐞
01:03:33Dan Nonneman:Ole, why not trophectoderm?
01:03:35Zhihua Jiang:Hi Ole, do you look at any gene switches from maternal to zygotic transition then? Thanks.
01:05:53Fiona McCarthy:@OleMadsen Could you please briefly describe the chicken intercross line used?
01:08:29Guillaume Devailly:@OleMadsen Do you know what are the specificities of the GSM pipeline compared to the nf-core/methylseq pipeline for DNA methylation data ?
01:13:37Emily Clark:@WesWarren on the subject of alternate assemblies dog is one example of what is currently possible with the genome browser for farmed animals e.g. Ensembl release 105 we updated the main reference to the Labrador reference genome and support alternate annotated assemblies for Boxer, Basenji and Great Dane. As Peter said we’re actively thinking now about how we tackle the explosion of new genomes for all the domestic animal species.
01:16:08Dan Nonneman:Placenta?
01:23:28Ole Madsen:@FionaMcCarthy, info about the line can be found here: https://www.ed.ac.uk/roslin/national-avian-research-facility/avian-resources/poultry-lines/advanced-intercross
01:25:55Guillaume Devailly:@Gabriel It seems theere is only one developmental stage per breed, but it is not the same between breeds. It this counfusion between breeds and developemental stages an issue for the analysis?
01:26:11Ole Madsen:@GuillaumeDevailly. A few additional downstream analysis/tools have been included, like Methylkit, CGmaptools
01:27:33Ole Madsen:@ZhihuaJiang. No we do not look at maternal to zygotic transition
01:30:51Ole Madsen:@DanNonneman. I do not know why we didn't consider trophectoderm, but I agree it will be interesting to look at as well.
01:31:56Annie Robic:@Gabriel, I am always surprised by the transcriptome of the testis which is always different from other tissues, but why only the testis and not the ovary?
01:33:26Jonah Cullen:@Gabriel Have you looked at any co-expression networks?
01:35:38Ole Madsen:@FionaMcCarthy, info about the line can be found here: https://www.ed.ac.uk/roslin/national-avian-research-facility/avian-resources/poultry-lines/advanced-intercross
01:36:04Ole Madsen:@GuillaumeDevailly. A few additional downstream analysis/tools have been included, like Methylkit, CGmaptools
01:36:11Elisabetta GIUFFRA:@DanNonneman, to add up: we didn't consider trophectoderm or other early phases: we had to choose among options and one of the ideas was also to complement other data from US on same stages
01:36:36Ole Madsen:@ZhihuaJiang. No we do not look at maternal to zygotic transition
01:36:52Emily Clark:@Gabriel and @Annie fetal ovary is highly transcriptionally active relative to juvenile and adult ovary and I think highlights how useful it is to include multiple developmental stages in annotation projects.
01:58:33Emily Clark:@Dailu sorry to lower your hand please go ahead and type your question for @Matthew in the chat.
02:07:44Ole Madsen:cool work, Ryan :-)
02:11:19Guillaume Devailly:@ChrisTuggle Impressive work! Any idea why EuroFAANG projects look so far behind the USDA funded-projects?
02:13:50Emily Clark:Question from @DominiqueRocha from Q&A box: @C. Tuggle: was the scATAC-seq generated at the same time with scRNA-seq using the multi-omics kit from 10x?
02:14:48Emily Clark:From @IreneKaplow from Q&A box Thanks for a great talk! You mentioned that there are pig-specific cell types relative to human in PBMCs. Have you investigated whether these help explain differences between pigs and humans.
02:15:53Emily Clark:**Please use the chat box rather than the Q&A box to post questions 🙂**
02:17:19Shenwen Gu:thank you
02:17:29Shenwen Gu:Yes
02:20:22Christopher Tuggle:Ryan- did you get the chat from Ole? He does methylation data as you probably know.
02:20:41Elisabetta GIUFFRA:@Chris, nice talk! Are the sc data already available in the FAANG data portal? And also: did you make use of deconvolution pipeines in comparing bulk and sc data from PBMCs?
02:22:04Ryan Corbett:Ole—thanks! Good to see you (hoping you are party of Host&Panelists and can see this message)
02:23:25Christopher Tuggle:Thanks Elisabetta! The scRNAseq for PBMC is submitted. The scRNAseq for tissues is being prepared and should be submitted in the next few weeks. We haven’t tried to deconvolution, but plan to do that when we have larger sample sizes
02:27:45Christopher Tuggle:@HUaijunZHou- can you determine whether your high number of transcripts relative to Ensembl is due to a larger number of tissues, or is your seq deeper?
02:32:11Irene Kaplow:Do the novel genes have orthologs in non-bovine mammals?
02:36:04Dailu Guan:Are transcriptomes sequenced by short-read or long-read? If short-read, how it is reliable in identifying splicing?
02:39:21Peter Harrison:From Dominque Rocha:
02:39:22Peter Harrison:@HZhou: WGBS is being done for how many tissues? At what targeted raw genome coverage (prior mapping)?
02:39:35Peter Harrison:@HZhou: WGBS is being done for how many tissues? At what targeted raw genome coverage (prior mapping)?
02:40:58Ishaku Haruna:Great talk @HZhou
02:47:24Huaijun Zhou:@Dominque a total of 71 samples from 33 tissues for WGBS with average of 356 million reads.
02:49:35Huaijun Zhou:@Dailu using short-read sequencing, but independently confirmed by long-read sequencing data.
02:51:42Ying Wang:@David Do you think Cut&Tag can replace ChIP-Seq assays?
02:52:25Guillaume Devailly:@DavidHawkins Is there a CUT&Tag equivalent of ChIP-qPCR? What QC do you do (if any) before sequencing the CUT&Tag samples?
