Taiwan University Architecture overview 2014.06 Slides by Liang Bo Wang Technical detail • VM for each user • or Hadoop cluster … don’t care • Communicate by defined API Web Frontend • Report generator (our part) • and user/analysis management (FXN)
Taiwan University Objectives for report generator • From view of either NGS service provider or web developer, this report generator should – Generate a static/local/portable analysis report for service user – View a summary report on web after submitted job finishes • Therefore our generator first takes local file input and produces local report • Host the report on web (basically) 2014.06 Slides by Liang Bo Wang
Taiwan University Manual for report generator • A manual for result interpretation • Use Sphinx for manual generation – Take plain text (reStructured Text, rst) into html pages – Easier than word to maintain • How/who/when to fill all the contents? 2014.06 Slides by Liang Bo Wang Link to detailed manual page
Taiwan University Development progress • Two pipelines result page status – Tuxedo: remain Cufflink, Cuffdiff – VarScan: almost done, changing lib to jsGrid • STAR and GATK are still in progress • Rewriting the generator to reuse same result subpage, such as FastQC, Tophat or BWA • Writing the parser for real result data (generated last week) 2014.06 Slides by Liang Bo Wang
Taiwan University Project progress • Co-IP contract modification – Received review (draft) from NTU consultant – Expect to get advice on contract modification today • Midterm report (due Jun. 27) – Received template from Dr. Dai – Cover NGS pipelines in use – Reuse the content back to the manual for result page – Most people here expected to be involved 2014.06 Slides by Liang Bo Wang
Taiwan University • DNA-Seq pipeline documentation and script request from FXN – Granted? • 1st poster on APCMBE (亞太醫工年會) (due Jun. 22) – Subject on NGS data reading and QC processing – Python package Nextbiopy – With a example use case – ARI co-author? • Done survey about further poster submissions 2014.06 Slides by Liang Bo Wang
Taiwan University Submission: GIW / ISCB Asia 2014 • Dec 15-17, Tokyo (http://www.jsbi.org/giw2014) – ISCB = International Society for Computational Biology – GIW = Genome Informatics • Proceedings acceptance such as Bioinformatics, BMC Genomics, JBCB and so on • Deadline – Jul 7 paper/oral – Aug 25 poster submission 2014.06 Slides by Liang Bo Wang
Taiwan University Submission: AYRCOB • Jan 19-20, 2015, Hsinchu (http://2015.ayrcob.org/) – AYRCOB = Asian Young Researchers Conference on Computational and Omics Biology • Jul 31 submission deadline (not sure poster or paper) • Not sure about the date for acceptance announcement • Too late? 2014.06 Slides by Liang Bo Wang
Taiwan University Future Plan • Make sure midterm report meet the deadline – Fill the content by collaboration • Continue on report generator / result parser development • Abstract for APCMBE poster • Initiate the structure for report manual 2014.06 Slides by Liang Bo Wang
Taiwan University Goal • Identify a diagnosis that human or current technology can do well but difficult to scale – Ex. Pathology analysis on biopsy – Ex. Some somatic mutation confirmed to develop cancer based on SNP microarray • Boost the prediction rate or speed up the prediction process by – Distributed computation – Multiple sources of data to do multiple instance learning 2014.06 Slides by Liang Bo Wang
Taiwan University Multiple Instance Learning • Some algorithm that Microsoft has been in leading position for years, used on video pattern recognition and linguistic analysis • Require data of same observation from multiple sources – Multiple sources of data (SNP, CNV, RNA-Seq, Chip-Seq data) – Large data size for model training (this will be a complex model anyway) • Asking if lab has such data sets (>100 samples) – Replied: small sample size in NGS data but not sure about microarray data – Better if accompanied with clinical data (concern about privacy issue) 2014.06 Slides by Liang Bo Wang
Taiwan University Workaround for large datasets • Search for large public dataset, but finding multiple source in public is hard • Take a look on projects like TCGA – Data policy has changed – For level I/II, require application for data access • Anyway, after some survey on such datasets, a summary about cancer genomic project 2014.06 Slides by Liang Bo Wang

Taiwan University Misc. • VM image Debian Jessie is added • RDP connection (Windows Remote Desktop) now possible • FreeNX -> X2go – FreeNX is outdated – X2go based on NoMachine NX3 protocol (2 concurrent connection limit?) – Some connection latency and failure encountered – Still resolving problems 2014.06 Slides by Liang Bo Wang
Taiwan University Misc. (cont’d) • Paper last week recap – Based on different event outcome, gene features can be more useful • CCRT miRNA reanalysis – Find differential expressed miRNA in different conditions – Still discussing methods 2014.06 Slides by Liang Bo Wang
