README  (Last Updated 10/01/2019)


   This README file describes the contents in this directory.

   This dataset contains raw, intermediate, and processed files for an 
Alzheimer brain Iso-Seq dataset. The library was sequenced on the 
Sequel II system and processed using SMRTLink 8.0 followed by community 
tool analysis. For more  information on Iso-Seq® methods[1], bioinformatics 
analysis, see the PacBio Iso-Seq GitHub[2] and additional references below.

300ng Total RNA - Alzheimer's Disease Brain Sample (BioChain lot #507294) 


Library Preparation: 
Iso-Seq® Express Template Preparation for Sequel® and Sequel® II Systems 

Sequel II System with Sequel II Binding Kit 1.0 and Sequel II Sequencing Kit 1.0 (4 rxn)

Run time: 
24hr movie + 2hr pre-extension 

SMRTlink 8.0 "IsoSeq" protocol, followed by mapping to hg38 reference genome 
and collapsed into  non-redundant transcript set.[3] 

Post-mapping filtering using SQANTI2 software[4].

Users wishing to immediately make use the processed, mapped, 
filtered results should use the following files:

|---- after-SQANTI2filter
|   |---- Alzheimer_IsoSeq2019.postFilter.abundance.txt 
|   |---- Alzheimer_IsoSeq2019.postFilter.faa 
|   |---- Alzheimer_IsoSeq2019.postFilter.fasta 
|   |---- Alzheimer_IsoSeq2019.postFilter.gtf 

UCSC Genome Browser Session:

We DO NOT recommend most users re-analyzing from raw (subreads.bam) 
or intermediate (FLNC) data.

Raw Subreads
The RawMovie/ folder contains the movie BAM file. 

|---- m64014_190506_005857.adapters.fasta 
|---- m64014_190506_005857.sts.xml 
|---- m64014_190506_005857.subreads.bam 
|---- m64014_190506_005857.subreads.bam.pbi 
|---- md5sums.txt

Intermediate FLNC Reads

The FullLengthReads/ directory contains the full-length, non-concatemer (FLNC) 
reads in both BAM and FASTQ format. 

|---- flnc.bam 
|---- flnc.fasta
|---- flnc.filter_summary.json 
|---- md5sums.txt

Mapped and Filtered Transcripts

The PolishedMappedTranscripts/ directory contains two subfolders. 

The "before-SQANTI2filter" directory contains the results of mapping the 
Iso-Seq output (full-length, high-quality isoform sequences) to the hg38 
reference genome, then collapsing the result using Cupcake [3] scripts with 
99% coverage and 95% identity cutoff. The collapsed results are delineated 
into the two samples based on the associated FLNC read count. The SQANTI2 
results (.classification.txt, .junctions.txt, and _sqanti_report.pdf)
are also included. 

The "after-SQANTI2filter" subdirectory contains the same files, but after 
running the SQANTI2 filtering script to remove library artifacts. For more 
information on the SQANTI2 filtering, see [4].
