    Script for extracting continues data

    Hello...

    I have continues sequence of data in type


    clk = 0.016 +- 0.018
    trp = 2.271 +0.043 +- 0.001
    amb G29 = 2.924 +- 0.012 nEpo = 4093
    amb G06 = 4.995 +- 0.014 nEpo = 3524
    amb G03 = -1.386 +- 0.015 nEpo = 848
    amb G21 = -0.403 +- 0.013 nEpo = 481
    amb G18 = -4.100 +- 0.013 nEpo = 377
    amb G22 = 9.674 +- 0.013 nEpo = 216
    amb G16 = -1.265 +- 0.016 nEpo = 5

    12-05-30 21:14:26 VSAK_PAM PPP 21:14:25.0 7 4640364.248 +- 0.014 2205651.817 +- 0.011 3767241.543 +- 0.011 NEU 0.075 -0.107 -0.078

    into a text file and i want to extract the time 21:14:26 and data after NEU into a new file in type like
    {
    "label": "VSAK_PAM_N",
    "data": [[211426, 0.075], etc]
    },
    { "label": "VSAK_PAM_E",
    "data": [[211426,-0.107], etc]
    },
    { "label": "VSAK_PAM_U",
    "data": [[211426,-0.078], etc]
    }
    also continues doing this until the file ends.


    Thanks

    What? What language is this? :-) What is the relationship of the first lines (amb ...) with the line below (12-05-30 ...)?

    If you just want to extract the time (with colons stripped), and save the label and data, given the latter line, in Perl, you could say:

    Code:
    my $line = '12-05-30 21:14:26 VSAK_PAM PPP 21:14:25.0 7 4640364.248 +- 0.014 2205651.817 +- 0.011 3767241.543 +- 0.011 NEU 0.075 -0.107 -0.078';
    
    my ($time, $label, $data) = $line =~ /\d\d-\d\d-\d\d (\d\d:\d\d:\d\d) (\S+) .*? NEU (.+)/;
    $time =~ s/://g;
    my @data = split /\s+/, $data;
    print record('N', $data[0], $time, $label);
    print record('E', $data[1], $time, $label);
    print record('U', $data[2], $time, $label);
    
    sub record {
        my ($suffix, $data_piece, $time, $label) = @_;
        return <<"EODATA";
    {
        "label": "${label}_$suffix",
        "data": [[$time, $data_piece], etc]
    }
    EODATA
    }
