== List of flagged samples run 1 == Author: Peter-Bram 't Hoen[[BR]] Date: 5-February-2014[[BR]] There are three fields in the metadatabase to flag samples that should not be used in the final analysis: QC of the sequencing, genotype concordance and contamination. Here we report the final list of samples which are flagged in the metadatabase.[[BR]] == QC flag == These three samples are flagged because of too low number of reads:[[BR]] Too few reads:[[BR]] AC1JV9ACXX-1-10[[BR]] AD1NE2ACXX-5-22[[BR]] BD1NW4ACXX-3-27[[BR]] [[BR]] Other reasons: See http://www.bbmriwiki.nl/wiki/BIOS_QualityControl/BIOS_QualityControlRun1 [[BR]] BD1NYRACXX-6-10 too low percentage of mapped reads, outlier on principal component 1,4,5,6[[BR]] AD2CJPACXX-8-9 low exon correlation, outlier on principal component 1,11,14[[BR]] BD1NR9ACXX-7-27 low percentage of mapped reads, outlier on principal component 4, likely degraded[[BR]] == Genotype concordance == This is the list of the samples from the different cohorts that have a mismatch between RNA and DNA genotypes that could not be corrected since there is no additional lab evidence suggesting a sample swap.

1One sample not part of RP3. 2Three LLS swaps identified by MixupMapper have been corrected. Additional evidence confirmed that these LLS samples were indeed swapped. These six samples are not included in the Genotype Discordance counts for LLS.

1Genotype information was extracted from the biobank genotype sample information files GoNL version 5 imputed data, directly extracted from the SRM. 2Numbers between brackets indicated the differences between number of person ids and genotype data available. 3Missing genotypes for: CODAM-2037, CODAM-2074, CODAM-2175 and CODAM-2555. 4Missing genotypes for: LL-LLDeep_0127 and LL-LLDeep_0519. 5These 10 samples are GoNL samples for which no genotype data was provided.

}}} === LLS update === For LLS the detected sample swaps were swapped back. The mixup mapper and genotype concordance check performed using the final sample sheets show no mixups and no strong outliers.
