File MEC-11-1215_sequence_data_bc.fasta This file contains all unique sequences found using the ewB/ewC primers. The sequences have been generated by the Illumina technology (GA IIx platform). Data collection: FRIEDERIKE BIENERT, SÉBASTIEN DE DANIELI, CHRISTIAN MIQUEL, ERIC COISSAC, CAROLE POILLOT, JEAN-JACQUES BRUN, PIERRE TABERLET Contact author: PIERRE TABERLET (pierre.taberlet@ujf-grenoble.fr) The header of each sequence contains: (i) the ID for the sequence (ii) the total number of occurrence of the sequence in the dataset (count) (iii) the number of occurrence in the different PCR (merged_sample) Code for identifying the PCR: (i) The first digit corresponds to the study site (C = Chartreuse; G = Grenoble) (ii) The second digit corresponds to the plot within a study site (iii) The third digit corresponds to the PCR (numbers 1 to 4: PCR using four different extractions as template; 5: mixing of the four different extracts as template) (iv) The fourth digit corresponds to the depth (S: surface sample; P: deep sample)
