Task 172: .EIS File Format

Upon searching, the .EIS file format is primarily associated with EIS Spectrum Analyser Project files, a standalone program for analysis and simulation of impedance spectra. However, detailed specifications for the file format are not publicly available, as they appear to be proprietary to the software and not documented in accessible sources. The project .eis files likely contain binary or structured data related to impedance spectra, fitted circuits, and analysis parameters, but without the exact structure, I cannot list all intrinsic properties or write accurate code for decoding, reading, writing, and printing them.

For impedance data files used by the software (which can have any extension, including .eis in some contexts), user discussions indicate a simple text format: the first line is the number of data points, followed by lines with real impedance (Z') and imaginary impedance (Z''). Frequency values may be included as a first column in some variants, but this is not confirmed. However, this is for input data, not the project .eis format itself.

Direct download links for .EIS files could not be found in public sources. The closest is the eisanalyser.zip archive at http://www.abc.chemistry.bsu.by/vi/analyser/program/eisanalyser.zip, which contains example project .eis files and data files, but it is not a direct .eis download.

Without the format specifications, I cannot complete parts 3-7, as any code would be speculative and potentially incorrect. If you provide the file format details or a sample .eis file, I can assist further.
