Comment: C: How to handle multi-TSS genes in Repitools?
... I wouldn't say that it's the correct approach, but if you are creating a heatmap plot with binPlots, it is best to reduce the number of rows in the heatmap. Having one row for each transcript would make its appearance more complex than necessary. I think including TSS unsupported by reads also could ...

Comment: C: How to handle multi-TSS genes in Repitools?
... Try processing one sample using RSEM and look at a few genes in IGV to see if the transcript with the majority of assigned reads seems plausible. I'm not convinced of the assertion that there are not enough reads to identify the most highly expressed transcript for each gene. ...

Answer: A: Splicing analysis with ASpli
... No, you shouldn't concatenate all of the samples belonging to a particular class. You can specify which class each sample belongs to by creating a targets data frame. ASpli also doesn't required paired samples, so there's no reason to force samples from the two classes to be paired somehow. ...

Answer: A: No BAM option in readAligned from the ShortRead package
... You should avoid using nucleR for your data analysis. The package depends on RangedData which has been "... has been discouraged in favour of GRanges or GRangesList objects since BioC 2.12, that is, since 2014.". Moreover, RangedData will be deprecated in April and probably removed entirely from IRa ...

Comment: C: Normalise counts when tumour samples have normal tissue contamination.
... Do you have an estimate of the normal fraction of the tumour samples from a clinician? If the fraction is about the same for all tumour samples, then it's best to do no normalisation. Fold changes would be under-estimated but would be in the correct order. ...

Answer: A: RUVnormalize- How to output a corrected expression matrix without negative value
... naiveRandRUV ​outputs the dataset with numbers compressed around 0. It's just a characteristic of the method. I like to avoid using RUV unless the PCA or MDS plot indicates that it's necessary. ...

Comment: C: Changing SVM-Kernal in geNetClassifier function
... No, the packages I mentioned don't output genes selected based on a multi-class criteria. You would need to write the function yourself. Of course, there are many classifiers you can use and different methods will give better classification performance for different datasets.   ...

Answer: A: Changing SVM-Kernal in geNetClassifier function
... No. It's also bad design that the developers implemented the cost value a constant. The optimal value would differ based on the input dataset. The algorithm basically does feature selection and inputs the chosen genes into to an SVM classifier. You can implement a similar analysis with ClassifyR or ...
