| - | SGA update | + | =====SGA update===== |
| + | * SGA is a memory efficient assembler | ||
| + | * It was possible to compute more compressed data | ||
| + | * The pipeline changed, since it was not easy to figure out how to run it | ||
| + | * It was necessary to make sure the parameters are running | ||
| + | * The group assembled one dataset, merged together | ||
| + | * SGA indexed each dataset separated | ||
| + | * Merging is complicated in a pairwise fashion, then two pairs were merged at a time | ||
| + | * Indexing all three sistinct submissions | ||
| + | * Pre-processed adapter trimming | ||
| + | * Duplicate-removal is later than indexing | ||
| + | * One issue the group found: SW018 and 19, same library are optical PCR duplicates that should be removed | ||
| + | * The overall duplication level is a problem | ||
| + | * Each datset was generated independently | ||
| + | * Then, removing duplicates should be done apart for each dataset | ||
| + | * The dataset is very complicated - there is big duplication rate across the dataset the group has | ||
| + | * Merging indexes - planning on pulling some stats from the grin engine to pull information | ||
| + | * The wall time is large | ||
| + | * A variant file with the bubble pop counted the contigs | ||
| + | * The group is planning on using the mate-pair data | ||
| + | * Do adapter removal and index removal - using skewer | ||
