Description of the data and file structure

The file reconstructed_maps.tar.gz contains all the recombination maps generated for the above paper in a gzipped tar archive that, after unpacking, follows the file structure assumed by the analysis code available at https://github.com/millanek/Hi-reComb_paper_analyses/.

File: reconstructed_maps.tar.gz

Description: The tar archive contains the following subfolders

• maps/simulated: These are the simulated maps underlying Fig. 2

• maps/reconstructed: These are the maps for Fig. 3

• maps/reconstructed/wBootstrap: These are the maps for Fig. 4

• maps/LD: These are the stickleback linkage disequilibrium (LD) -based maps underlying the comparisons in Fig. 5

• maps/reconstructed/wDepth: This file contains the effective depth data underlying Supplementary Fig. 1

Variables:

Each recombination map (for each chromosome) has three tab-separated columns:
1) "start coordinate", 2) "end coordinate", and 3) "recombination rate per bp (r)" 

The values of "nan" in all the files indicate that the recombination rate could not be determined for a particular region of the chromosome (e.g., because of the 'edge effect' near chromosome ends).

In the folder 'maps/LD', the LD-based map for stickleback follows the same format as the other maps, with the exception that a single file contains maps for all the chromosomes, and the first column is the chromosome ID.

In the folder 'maps/reconstructed/wBootstrap', the files include the same three columns followed by an additional 50 columns with recombination rate estimates based on bootstrap replicates.

In the folder 'maps/reconstructed/wDepth', we provide a file for chromosome 16 of Neolamprologus multifasciatus with information on effective depth, underlying Supplementary Fig. 1. More specifically, the columns are:
'pos' - position on chromosome 16
'ratePerBp' - estimated recombination rate at that position
'EffectiveDepth' - effective depth, plotted in Supplementary Fig. 1
'directReadCoverageConcord' - The number of read pairs bounded by this site indicates the absence of a crossover (X=N)
'directReadCoverageDiscord' - The number of read pairs bounded by this site that indicate crossovers (X=C)

Sample IDs:

T2-2 Neolamprologus multifasciatus
H3C2 Astatotilapia calliptera
AN01 Astatotilapia nubila
H5a2 Aulonocara stuartgranti
WB1 Gasterosteus aculeatus (from Walby Lake in Alaska)

All file names are identified with these IDs
