Help for downloading cisTarget d

cis目标数据库文件相当大（其中大多数为1-100GB）。

为了避免损坏或不完整的下载，文件可以下载与zsync_curl（这基本上是rsync超过HTTP（S））。

它允许恢复已经部分下载的数据库，并且只会下载丢失或重新下载损坏的块。

首选：下载带有zsync_curl的数据库

您可以从源下载静态链接的自编译版本：

A） 下载静态链接zsync_curl

Download (with wget or curl):
wget https://resources.aertslab.org/cistarget/zsync_curl
# curl -O https://resources.aertslab.org/cistarget/zsync_curl

# Make executable:
chmod a+x zsync_curl

# Display full path to zsync_curl.
ZSYNC_CURL="${PWD}/zsync_curl"
echo "${ZSYNC_CURL}"

B） 从源头编译zsync_curl

按照 https://github.com/AppImage/zsync-curl 上的生成说明操作

# Display path to zsync_curl:
ZSYNC_CURL='zsync_curl'
echo "${ZSYNC_CURL}"

下载包含zsync_curl的数据库

# Specify database name:
feather_database_url='https://resources.aertslab.org/cistarget/databases/homo_sapiens/hg19/refseq_r45/mc8nr/gene_based/hg19-500bp-upstream-7species.mc8nr.feather'

# Download database with zsync_curl:
"${ZSYNC_CURL}" "${feather_database_url}.zsync"

备选方案：直接下载数据库

# Specify database name:
feather_database_url='https://resources.aertslab.org/cistarget/databases/homo_sapiens/hg19/refseq_r45/mc8nr/gene_based/hg19-500bp-upstream-7species.mc8nr.feather'

feather_database="${feather_database_url##*/}"

# Download database directly (with wget or curl):
wget "${feather_database_url}"
# curl -O "${feather_database_url}"

# Download sha256sum.txt (with wget or curl):
wget https://resources.aertslab.org/cistarget/databases/sha256sum.txt
# curl -O https://resources.aertslab.org/cistarget/databases/sha256sum.txt

# Check if sha256 checksum matches for the downloaded database:
awk -v feather_database=${feather_database} '$2 == feather_database' sha256sum.txt | sha256sum -c -

# If you downloaded mulitple databases, you can check them all at onces with:
sha256sum -c sha256sum.txt
