1. stPeakList.pl

Check the peak list matches

Check the peak list matches

sparky 0/test.ucsf

Prepare files

Make standard peak list

stPeakList.pl 0/test.ft2 peak_list_SPARKY.list > peak_list_SPARKY.tab
cat peak_list_SPARKY.tab

Find *.ft2 files

ls -v -d -1 */*.ft2 > ft2_files.ls
cat ft2_files.ls

Measure heights

seriesTab -in peak_list_SPARKY.tab -out peaks_list_max_standard.ser -list ft2_files.ls -max
cat peaks_list_max_standard.ser

Extract the spectra settings from Varian procpar file

set RELAXT=`awk '/^relaxT /{f=1;next}f{print $0;exit}' procpar`; echo $NCYCLIST
set SFRQ=`awk '/^sfrq /{f=1;next}f{print $2;exit}' procpar`; echo $SFRQ

foreach I (`seq 2 ${#RELAXT}`)
  set T=${RELAXT[$I]}; echo $T $SFRQ >> relaxt.txt
end

cat relaxt.txt

Measure RMSD in spectra

Measure the backgorund noise .22RMSD.22 in each of the .ft2 files

Very fast way - RMSD via nmrpipe showApod

We can also use the showApod rmsd.

set FIDS=`cat ft2_files.ls`
set OUT=${PWD}/apod_rmsd.txt
set CWD=$PWD
rm $OUT

foreach I (`seq 1 ${#FIDS}`)
set FID=${FIDS[$I]}; set DIRN=`dirname $FID`
cd $DIRN
set apodrmsd=`showApod *.ft2 | grep "REMARK Automated Noise Std Dev in Processed Data:" | awk '{print $9}'`
echo $apodrmsd $DIRN >> $OUT
cd $CWD
end
cat $OUT

paste relaxt.txt $OUT > settings.txt
