Question

[Bioinfonext]

Hi,

I have got two tab demilated files; count.txt and metadata.txt. I would like to renmae the count.txt header based on the metadata.txt 5th Column (SampleType). Could anyone please suggest how I can do it by using R or unix command?

Count .txt

Generate a sed pattern with awk . something like:

sed -f <(awk '/^[^ \t]/ {printf("/^[ \\t]/s/%s/%s/\n",$1,$5);}' Metadata.txt) Count.txt

please note that using sed may have side effects if your header have samples likes Root-T1 and Root-T11 (thet both match the pattern Root-T1 )

thanks Pierre,

For 4th column, this command working perfectly, but for 5th column result file look like below;

Rainfed

If I open the result file based on 5th column with vi command it like this; I am not sure how it got ^M character.

Irrigated^M     Irrigated^M     Irrigated^M     Irrigated^M     Irrigated^M     Rainfed^M       Rainfed^M       Rainfed^M       Rainfed^M       Rainfed^M       Irrigated^M     Irrigated^M     Irrigated^M     Irrigated^M     Irrigated^M     Rainfed^M       Rainfed^M       Rainfed^M       Rainfed^M       Rainfed^M       Irrigated^M     Irrigated^M     Irrigated^M     Irrigated^M     Irrigated^M     Rainfed^M       Rainfed^M       Rainfed^M       Rainfed^M       Rainfed^M

it works perfectly after I have corrected the metadata file by using below command.

cat metadata.txt | tr "\r" "\n" > metadata.txt

Many thanks

Is it also possible to arrange all Irrigated column together and then rainfed?

Many thanks
