It seems that the old version of blast (blastall) can make use of multithread processing and speed up things whereas new blast+ versions get stuck to using single thread even when you set the parameters to ask for more threads.
Therefore, I would like to download and use the old blast. The problem is that I cannot seem to find in the ncbi ftp.
Can anyone direct me to the executable file for blastall? Alternatively, can I still use blastall parameters somehow in the new blast+?
