We're willing to help with good advice. But you need to ask a specific question. What have you tried? Where does it go wrong? Are there any error messages? Post a snippet of the text file you're using and the relevant portion of your code.

i was trying but the problem is the parsing of uploaded file :/ in example :

That's what I was trying to get at. What EXACTLY is the problem?

I don't know how place data in right side

I'm afraid that's not a good enough explanation of the problem you are facing to give you a good answer. Is the problem that you have no idea how to begin? In that case it will be difficult to help, because we can't teach you programming from scratch. Why don't you post what code you have so far.

You do realize that you are the only one that understands this statement, don't you? How do the contents of the file "map" to your desired output?

Put your keyboard away. What does "parsing the file" look like using paper and pencil?

This is a script to do this in ruby :

#!env ruby

def parse(text)
text.split(',').map do |item|
key, value = item.split(':')
[key.to_i, value.to_f]
end.to_h
end

input_data = File.read(ARGV[0]).gsub("\r", "")

id = nil
entries = {}

input_data.split("\n").each do |line|
columns = line.split("|")

id = columns[0].to_i if columns.size == 3
entries[id] ||= {}

if columns.size == 3 || columns.size == 1
entries[id].merge! parse(columns.last)
elsif columns.size != 0
puts "? #{line}"
end
end

entries.sort_by { |k,v| k }.each do |key, weights|
puts
puts
puts "# neuron #{key}"

puts "source\tweight"
weights.sort_by { |k, v| k }.each do |source, weight|
puts "#{source}\t#{weight.to_s.gsub('.',',')}"
end
end

Thanks for help !!!
