  1. Is the article looks straightforward to you? If not, why?
  2. In general sense, do you prefer interactive web-based software or command-driven ones, why?
  3. Have you ever used other softwares for building taxonomic tree or phylogenetic tree with metadata? How do you think this GraPhlAn compared with what you used?
  4. What do you think make a software more attractive to researchers? e.g., usefulness, detailed documentations, active support group and so on?
  5. Based on your understanding of this article, what part do you think does not make sense? What kind of improvements you will do if you were the developer of this software?

1)Were you able to get the program to work? Was it user-friendly?

2)Do you believe this program adequately predicts post-translational modification of proteins identified through mass spec? Why, why not?

3)Can you think of any ways in your own research or research generally where this tool could be applicable?

4)What do you feel could have been included in the paper to make their argument more convincing? Do you believe this program is better than its predecessors, or did the fail to convince you?

1- Were you successful in submission a raw sequence data to be analyzed?

2- Did you receive any error after sequence submission? Did you get it solved?

3- Were the obtained results as the same as your expected outcome?

4- How do you see the efficiency of the web-based platform and its simplicity/complexity in data analyses for virus discovery purposes?

5- According to your experience with this tool, what would be your suggestion to add to the four essential keys of a universal bioinformatics tool mentioned in the paper?

    • Article Link: oPOSSUM: identification of over-represented transcription factor binding sites in co-expressed genes

    • For those of you familiar with statistical analyses, do you think that the use of both a Z-score analysis and a one-tailed fisher exact probability test is sufficient to classify a gene as “statistically over-represented” or would you suggest another method?

    • Does the use of human and mouse orthologs make sense as a basis for the database?

    • Are you convinced that oPOSSUM reduces the number of false positives you might find when using the JASPAR database alone?

    • Did you have any technical issues with the program and were you able to overcome them? If so what were they and how did you get around the issue?

  • I will be presenting on an app that performs DeSeq2 gene expression analysis and shows some cool graphics using the SARtools package. The paper below describes the DeSeq2 analysis and customization. If you want to play with the app before class, it can be found in the cyverse.org discovery environment. The app is called "DESeq2 (multifactorial pairwise comparisons)."
