    MetaPORE analysis of Illumina MiSeq data from samples containing CHIKV and EBOV. Taxonomic donut charts were generated from Illumina MiSeq data corresponding to the Chik1 run ( a ) and Ebola1 run ( b ) using the MetaPORE bioinformatics analysis pipeline. The total number of MiSeq reads analyzed is shown in the center of the donut. Note that given computational time constraints, only a subset of reads (n = 100,000) was analyzed using MetaPORE. Coverage and pairwise identity plots were generated from MiSeq CHIKV reads from the Chik1 sample (248,677 of 3,235,099 reads, 7.7 %) ( c ), or EBOV reads from the Ebola1 sample (20,820 of 2,743,589 reads, 0.76 %) ( d ), identified using SURPI analysis and LASTZ mapping {Harris, 2007 #34} at an e-value of 10-5 to the closest matching reference genome.

    Principal component analysis of microbial communities on strawberry leaves. First two Principle Components derived from correlation in individual OTU abundance among individual samples for bacteria ( a ) and fungi ( b ) – the OTU abundance was calculated as log 2 (x i + 1)/∑(log 2 (x i + 1)) for a given sample where x is the original counts value for the i th OTU. The two clusters were derived from the weighted UniFrac distance using the Ward method. Strawberry plants of cv. Vibrant grown in the open or under protection were sprayed or not sprayed with Serenade (a commercial formulated product of Bacillus subtilis ); leaves were sampled 4 hours (4H) and 8 days (8D) after spraying. In addition, leaves emerged after spraying were also sampled on day 8. Microbial populations on the phyllosphere were profiled with the Illumina MiSeq.

    Strategy for single-cell TCR sequencing and phenotyping, and determination of TCR-sequencing efficiency. ( a ) Strategy for simultaneous TCR-sequence determination and phenotyping of single, sorted T cells. Single T cells were sorted into 96-well plates. The initial RT-PCR reaction (reaction 1) uses 76 TCR primers and 34 phenotyping primers. An aliquot of the product of reaction 1 is used for two separate second nested PCR reactions (reaction 2), one for TCR sequencing and one for phenotyping. Using an aliquot of reaction 2 product as a template, a third PCR reaction is performed that incorporates individual barcodes into each well and enables subsequent sequencing using the Illumina MiSeq platform. For TCR sequencing, the third reaction can be split into separate TCRα and TCRβ reactions (for optimal efficiency), or the two TCR chains can be included in a single reaction. The products of reaction 3 are then combined and sequenced using the Illumina MiSeq platform. ( b,c ) Accuracy and efficiency of TCR sequencing using this method. ( b ) Strategy used to validate TCR sequencing. Into each 96-well test plate, individual human peripheral blood T cells were sorted into 80 wells (gray). Single Jurkat T cells were sorted into eight other wells (red), and the remaining eight wells (black) were left empty (blank). For sequencing of these test plates, reaction 3 was initially performed separately for TCRα and TCRβ (split). It was also repeated with TCRα and TCRβ amplified together in the same reaction (combined). ( c ) Efficiency of TCRα and TCRβ sequencing in split or combined formats. Plate 1 contained 80 single CD45RA+ CD4+ TCRαβ+ T cells, and plate 2 contained 80 single CD4+ or CD8+ TCRαβ+ T cells sorted from periphera blood of the same healthy human donor. Identical Jurkat sequences were obtained from all Jurkat wells. No sequences were obtained from any empty wells.

    Expenditures of time for assessing levels of human faecal contamination in water samples with different approaches. The first three bars demonstrate the amount of time needed with the experimental settings applied in this study, while the last two bars show the feasible time requirements of the Nanopore-based approach with settings optimised based on the results of this study. Computing time for sequence and data analysis (i.e., the steps after the actual sequencing) was calculated based on the computing power of 16 threads. The arrow under the MiSeq timeline indicates the starting point if only five samples had been processed. Time for the Colilert-18® test would not change regardless of sample size. The time for the barcoding procedure in the Nanopore library preparation was segmented from the library preparation hours and marked with “B”. The base-calling procedure for Nanopore can be conducted while the sequencing is ongoing. The optimised Nanopore timelines (the 4th and 5th bars) demonstrate the feasible time usage for assessing five water samples by using different barcoding approaches (ligation-based or transposase-based) with the sequencing depth of 1,000 reads per sample.

( a ) Following isolation of lymphocyte messenger RNA, an IgM library is constructed using either 5′RACE or multiplex PCR and sequenced using the Illumina MiSeq system.

( c ) Windowed cluster analysis, (upper left panel), showing sequences assigned to a reference gene and binned in 2% windows to allow discrete consensus building. Linkage cluster analysis (upper right panel) of a subset of 300 sequences. Rows and columns of the matrix correspond to sequences. The colour at an intersection of a row and a column gives the number of differences between the corresponding sequences. The dendrograms (to the left and above, both identical) show the hierarchy found according to hierarchical clustering. Sequences are rearranged to conform to the clustering, putting similar sequences adjacent to each other. Clusters of similar sequences are visible as bright squares along the main diagonal. Colouring on the left indicates clusters detected by IgDiscover (one colour per cluster). Following consensus building, candidate germline sequences are processed using the pregermline filter, resulting in a new VH database. The assignment, clustering, consensus-building and pregermline filter steps are repeated for a set number of iterations using each new VH database for initial assignment. Examples of windowed cluster histograms (left two lower panels) and linkage cluster plots (right two lower panels) using databases containing newly identified candidate germline V genes.
