Extract lines with min value, using two field separators.

I have a file with two ID columns followed by five columns of counts in fraction form. I'd like to print lines that have a count of at least 4 (so at least 4 in the numerator, e.g. 4/17) in at least one of the five columns.

Input file:
Code:
comp51820_c1_seq1 693 0/29 0/50 0/69 0/36 0/31
comp51820_c1_seq1 694 0/29 0/54 1/67 0/34 0/30
comp51820_c1_seq1 710 0/11 0/36 0/14 0/25 4/17
comp51820_c1_seq1 711 1/11 2/35 6/14 5/25 6/17

Desired output:
Code:
comp51820_c1_seq1 710 0/11 0/36 0/14 0/25 4/17
comp51820_c1_seq1 711 1/11 2/35 6/14 5/25 6/17

I'm still new but I'm thinking awk could help, using "/" as the field separator. But I'm not sure how to keep the spaces as field separators as well. I have been looking into split, but it's not clear (to me) it will help.

Any ideas out there? I'm not great at parsing files yet and it's quite a bottleneck in my work (which obviously is not programming)...

NAME
cut - select out columns of a file SYNOPSIS
cut [ -b | -c] list [file...] cut -f list [-d delim] [ -s] OPTIONS
-b Cut specified bytes -c Select out specific characters -d Change the column delimiter to delim -f Select out specific fields that are separated by the -i Runs of delimiters count as one -s Suppres lines with no delimiter characters, when used EXAMPLES
cut -f 2 file # Extract field 2 cut -c 1-2,5 file # Extract character columns 1, 2, and 5 cut -c 1-5,7- file # Extract all columns except 6 DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched" Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa- rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man- ual page. SEE ALSO
