The data is arranged into subfolders for each run of the model.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Data for figures 2 and 3 can be found in the folders
final_n_sd_'standard deviation'_VT_'tidal volume ml/kg'_C_'degree of network collapse'.dat
For each run there are three files:
initial.dat, a record of the initial conditions for the simulation for all 63 airways arranged in order (generation 11, gen 12, gen 13 etc)
column 1: dimensional height of the airway (cm) (denoted h_j^{(k)} in the paper)
column 2: dimensional width of the airway (cm) (denoted z_j^{(k)} in the paper)
trace.dat, a time trace of key variables
column 1: dimensionless time
column 2: dimensionless pressure
column 3: dimensionless network volume
column 4: dimensionless volume of upper airways (generations 0-10)
column 5: dimensionless total volume of the lung
column 6: dimensionless maximal pressure gradient in generation 11
column 7: dimensionless maximal pressure gradient in generation 12
column 8: dimensionless maximal pressure gradient in generation 13
column 9: dimensionless maximal pressure gradient in generation 14
column 10:dimensionless maximal pressure gradient in generation 15
column 11:dimensionless maximal pressure gradient in generation 16
column 12:number of recruited airways
column 13:number of complete paths recruited through network
damage.dat, a record of the maximal damage in each airway
row 1: number of airways in that generation where dimensional damage exceeds 10^3.5 (dyn cm^{-2} mum^{-1})
row 2: number of airways in that generation where dimensional damage exceeds 10^4 (dyn cm^{-2} mum^{-1})
row 3: number of airways in that generation where dimensional damage exceeds 10^4.5 (dyn cm^{-2} mum^{-1})
row 4: number of airways in that generation where dimensional damage exceeds 10^5 (dyn cm^{-2} mum^{-1})
column 1: generation 11
column 2: generation 12
column 3: generation 13
column 4: generation 14
column 5: generation 15
column 6: generation 16

Data for figure 4 can be found in folders
final_dam_n_sd 'standard deviation' _VT_10_C_'degree of network collapse'.dat
Data is arranged in an identical way to data for figures 2 and 3. However, there is an additional file
airwaydamage.dat, measure of damage in each of recruited airways arranged sequentially in order of recruitment
column 1: generation number of recruited airway
column 2: rank in order of recruitment, 1 first, 2 second etc
column 3: dimensionless mean maximal airway area for that generation
column 4: dimensionless maximal airway area for that airway
column 5: dimensionless mean maximal pressure gradient for airways in that generation
column 6: dimensionless maximal pressure gradient for that airway
column 7: index of recruited airway

Data for figure 5 can be found in folders
final_n_sd_'standard deviation'_VT_'tidal volume ml/kg'_C_'degree of network collapse'_PEEP_'peep value cmH_2O'.dat
Data is arranged in an identical way to data for figures 2 and 3
