.ace and doube quotes -- a nightmare
Summary:
do not use double quotes in .ace data.
Reason:
if there are double quotes in the data it
is not possible to dump the database and get
back to same state by reloading that dump
Method:
using ACEDB 3.1 as of 14.July 94
or the
with ACEDB 3.3 from_ncbi as of 94-07-30 with:
the model:
?Sequence other_features ?Text Text Text Text
or
?Motif Text Text Text (from ACEDB 3.3)
read .ace file:
Sequence "a1"
other_features "1a" "2" "3"
other_features "\"1b" "2" "\"3"
other_features "\""1c" "2" "\""3"
displayed as:
a1 Attach... Quit
Features other_features 1a 2 3
1b 2 3
"1c 2 "3
dumped as:
// data dumped from tree display
Sequence : "a1"
other_features "1a" "2" "3"
other_features "1b" "2" "3"
other_features ""1c" "2" ""3"
reading that dump is displayed as:
a2 Attach... Quit
Features other_features 1a 2 3
1b 2 3
EMBL data contains a lot of double quotes which I would like
to keep. I think this is such a silly bug and should be fixed.
The problem is probably with these lines in w1/freesubs.c:
else if (*in == '"') /* restore backslash for freeword to read */
{ *in = '\\' ;
*++in = '"' ;
}
why is " replaced by \ in the current position and the next position set to " ?
