3. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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)
4. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National Taiwan University Workflow (view by functions) 
   
   2014.06 Slides by Liang Bo Wang Explicitly, we are working on this
5. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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
6. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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
7. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National Taiwan University How Sphinx works 
   
   2014.06 Slides by Liang Bo Wang by Sphinx and docutils from RST files
8. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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
9. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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
10. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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

11. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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

13. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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
14. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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

15. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National Taiwan University MRSA Research Possible goal Available large datasets in lab ICGC related cancer project intro 
    
    2014.06 Slides by Liang Bo Wang
16. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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
17. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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
18. Bioinformatics and Biostatistics Core, NTU Center of Genomic Medicine, National 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
