1 These are Galaxy wrappers for common unix text-processing tools
|
|
2 ===============================================================
|
|

|
|
4 The initial work was done by Assaf Gordon and Greg Hannon's lab ( http://hannonlab.cshl.edu )
|
|
5 in Cold Spring Harbor Laboratory ( http://www.cshl.edu ).
|
|
6
|
|
7
|
|
8 The tools are:
|
|
9
|
|
10 * awk - The AWK programmning language ( http://www.gnu.org/software/gawk/ )
|
|
11 * sed - Stream Editor ( http://sed.sf.net )
|
|
12 * grep - Search files ( http://www.gnu.org/software/grep/ )
|
|
13 * sort_columns - Sorting every line according to there columns
|
|
14 * GNU Coreutils programs ( http://www.gnu.org/software/coreutils/ ):
|
|
15 * sort - sort files
|
|
16 * join - join two files, based on common key field.
|
|
17 * cut - keep/discard fields from a file
|
|
18 * unsorted_uniq - keep unique/duplicated lines in a file
|
|
19 * sorted_uniq - keep unique/duplicated lines in a file
|
|
20 * head - keep the first X lines in a file.
|
|
21 * tail - keep the last X lines in a file.
|
|
22
|
|
23 Few improvements over the standard tools:
|
|
24
|
|
25 * EasyJoin - A Join tool that does not require pre-sorted the files ( https://github.com/agordon/filo/blob/scripts/src/scripts/easyjoin )
|
|
26 * Multi-Join - Join multiple (>2) files ( https://github.com/agordon/filo/blob/scripts/src/scripts/multijoin )
|
|
27 * Find_and_Replace - Find/Replace text in a line or specific column.
|
|
28 * Grep with Perl syntax - uses grep with Perl-Compatible regular expressions.
|
|
29 * HTML'd Grep - grep text in a file, and produced high-lighted HTML output, for easier viewing ( uses https://github.com/agordon/filo/blob/scripts/src/scripts/sort-header )

32 Requirements
|
|
33 ------------
|
|
34
|
|
35 1. Coreutils vesion 8.19 or later.
|
|
36 2. AWK version 4.0.1 or later.
|
|
37 3. SED version 4.2 *with* a special patch
|
|
38 4. Grep with PCRE support
|
|
39
|
|
40 These will be installed automatically with the Galaxy Tool Shed.

44 NOTE About Security
|
|
45 -------------------
|
|
46
|
|
47 The included tools are secure (barring unintentional bugs):
|
|
48 The main concern might be executing system commands with awk's "system" and sed's "e" commands,
|
|
49 or reading/writing arbitrary files with awk's redirection and sed's "r/w" commands.
|
|
50 These commands are DISABLED using the "--sandbox" parameter to awk and sed.
|
|
51
|
|
52 User trying to run an awk program similar to:
|
|
53 BEGIN { system("ls") }
|
|
54 Will get an error (in Galaxy) saying:
|
|
55 fatal: 'system' function not allowed in sandbox mode.
|
|
56
|
|
57 User trying to run a SED program similar to:
|
|
58 1els
|
|
59 will get an error (in Galaxy) saying:
|
|
60 sed: -e expression #1, char 2: e/r/w commands disabled in sandbox mode
|
|
61
|
|
62 That being said, if you do find some vulnerability in these tools, please let me know and I'll try fix them.

65 Installation
|
|
66 ------------
|
|
67
|
|
68 Should be done with the Galaxy `Tool Shed`_.

73 ----
|
|
74 TODO
|
|
75 ----
|
|
76
|
|
77 - unit-tests
|
|
78 - uniqu will get a new --group funciton with the 8.22 release, its currently commended out
|
|
79 - also shuf will get a major improved performance with large files http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=commit;h=20d7bce0f7e57d9a98f0ee811e31c757e9fedfff
|
|
80 we can remove the random feature from sort and use shuf instead
|
|
81 - move some advanced settings under a conditional, for example the cut tools offers to cut bytes
|
1
|
82 - cut wrapper has some output conditional magic for interval files, that needs to be checked
|
|
83 - comm wrapper, see the Galaxy default one
|
2
|
84 - evaluate the join wrappers against the Galaxy ones, maybe we should drop them
