Evaluation of case study 1 (grapevine leaves) set of assemblies using PCA plots coloured by clusters. a PCA plot of the first two dimensions with the three significant clusters found by HCPC analysis marked as green (3.1), red (3.2) and black (3.3). The primary assembly ctOasesK35 and the scaffolded assembly scOasesK35 are boxed in blue to highlight the improvement of OASES when contigs are scaffolded. b Tree of assemblies where clusters are boxed in the same colours as a. Cluster 3.1 (green box): the 2 plant reference transcriptomes and the 3 OASES scaffolded assemblies. Cluster 3.2 (red box): 13 assemblies, 9 of them being scaffolded assemblies. Cluster 3.3 (black box): 14 assemblies, 11 of them being primary assemblies
