Specification Table 

Subject	Biochemistry.
Specific subject area	Structural Bioinformatics, proteins disorder.
Type of data	A collection of atom coordinates in the pdb format, tables, text files and Figures.
How data were acquired	A survey of the Protein Ensemble Database (PED).
Data format	Raw, analysed and filtered
Parameters for data collection	A Protein Ensemble Database survey was performed in march 2019. The data set consists of PED stores 25,473 protein structures of 60 ensembles in 24 entries in the Protein Data Bank (pdb) format. The atom coordinate files were cleaned and treated as described below and as such may be used for further automatic analysis.
Description of data collection	Every entry of PED was analysed, i.e. some have inconsistencies. Then, all cleaned files were used for Protein Blocks (PBs) assignment, the frequency of each PBs was calculated, and local entropy was computed. All files are provided. In a similar way, DSSP was used to assign secondary structure and solvent accessibility for each residue. The dataset also collects disorder prediction generated from DisoPred and PrDOS webserver. Flat text files are provided for simple use and some Figures for better visualisation.
Data source location	University of Paris, Paris, France.
Data accessibility	Data is given in the paper. It can as well be downloaded from: http://www.dsimb.inserm.fr/∼debrevern/RESEARCH/IDP-PB/.
